Special Relativity and Schwarzschild Radius
November 5th, 2022
1. A particle is measured to have a kinetic energy that is four times its rest as energy. How fast is the particle moving? Express the speed as a fraction of c.
2. Write down the transformations that relate the electric field E and the magnetic field B in two different inertial frames. Use your result to show that E*B is the same for all inertial observers. You may choose the motion to be in the x-direction if you wish.
3. Define the Schwarzschild radius of a black hole and give a brief description of its significance.
