Electric Field of a Non Uniformly Charged Sphere01:22

Electric Field of a Non Uniformly Charged Sphere

2.0K
Gauss's law states that the electric flux through any closed surface equals the net charge enclosed within the surface. This law is beneficial for determining the expressions for the electric field for a particular charge distribution if the electric flux is known.
Consider a non-uniformly charged sphere, for which the density of charge depends only on the distance from a point in space and not on the direction. Such a sphere has a spherically symmetrical charge distribution. Here, the electric...

The Principle of Superposition and the Gravitational Field01:17

The Principle of Superposition and the Gravitational Field

1.8K
The principle of superposition applies to gravitational forces of objects that are sufficiently far apart. It states that the net gravitational force on a point object is the vector sum of the gravitational forces on it due to various objects. The principle helps calculate the force by listing the individual forces and then vectorially summing them up. However, it should be noted that the principle of superposition is not always apparent. In the presence of a second force, the first force could...

Speed of a Transverse Wave01:13

Speed of a Transverse Wave

2.2K
The speed of a wave depends on the characteristics of the medium. For example, in the case of a guitar, the strings vibrate to produce the sound. The speed of the waves on the strings and the wavelength determine the frequency of the sound produced. The strings on a guitar have different thicknesses but may be made of similar material. They have different linear densities, and the linear density is defined as the mass per length.
One of the key properties of any wave is the wave speed. Light...

First Law: Particles in Two-dimensional Equilibrium01:18

First Law: Particles in Two-dimensional Equilibrium

11.8K
Recall that a particle in equilibrium is one for which the external forces are balanced. Static equilibrium involves objects at rest, and dynamic equilibrium involves objects in motion without acceleration; but it is important to remember that these conditions are relative. For instance, an object may be at rest when viewed from one frame of reference, but that same object would appear to be in motion when viewed by someone moving at a constant velocity.
Newton's first law tells us about...

Perpendicular-Axis Theorem01:16

Perpendicular-Axis Theorem

3.9K
The perpendicular-axis theorem states that the moment of inertia of a planar object about an axis perpendicular to its plane is equal to the sum of the moments of inertia about two mutually perpendicular concurrent axes lying in the plane of the body.
Consider a circular disc of mass M and radius R lying along an x-y plane. The origin lies at the center of the disc, and the z-axis is perpendicular to the disc's plane. All three axes coincide at the disc's center. The moment of inertia of this...

Motion Of A Charged Particle In A Magnetic Field01:22

Motion Of A Charged Particle In A Magnetic Field

6.0K
A charged particle experiences a force when moving through a magnetic field. Consider the field to be uniform and the charged particle to move perpendicular to it. If the field is in a vacuum, the magnetic field is the dominant factor determining the motion. Since the magnetic force is perpendicular to the direction of motion, a charged particle follows a curved path. The particle continues to follow this curved path until it forms a complete circle. Another way to look at this is that the...

This summary is machine-generated.

In the tensionless limit of bosonic string theory, a null string emerges with infinite acceleration. This reveals null string complementarity, showing open string physics from closed strings via D instantons or D-25 branes.

  • Theoretical Physics
  • String Theory
  • Quantum Gravity

Background:

  • Bosonic string theory describes fundamental interactions using vibrating strings.
  • The tensionless limit and Rindler horizons are key concepts in exploring string dynamics.

  • Analysis of the limit of infinite acceleration and Rindler horizon interaction.
  • Observer-dependent analysis of string dynamics in different reference frames.

Main Results:

  • The null string emerges in the tensionless limit at infinite acceleration.
  • Null string complementarity provides two distinct, observer-dependent descriptions of open string physics.
  • The closed string vacuum transforms into a D instanton for inertial observers and a D-25 brane for accelerated observers.
