Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.

Conducting spherical shell of radius b, located at the origin, has a potential
V=V,b/r for r>b and V, for r<b. Calculate the stored energy for b=1.3 m and V=30 V.
(take potential equals to zero at infinity).

Interaction between an electric field and a magnetic field.

Expert Solution

Step 1

Given information:

Here, V is the potential outside the conducting shell, b is the radius of the shell, and V₀ is the potential inside the shell.

Step 2

Since the potential inside the conducting shell is constant, thus the electric field (E_in) inside the shell is zero.

The electric field (E_out) outside the shell can be calculated as,
