Question

- A parallel plate capacitor in sy plane of frame S has a surface charge density o. Find the
speed with which the frames should move so that the charge density measured from S'is
twice the value in frame S. (c is speed of light)
(a) 0.95 c
(b) 0.850
(c) 0.79
(d) 0.866 c​

Answer 1

Explanation:

that spaceship A has velocity ux = 0.50c in S . Spaceship A moves with velocity. 0.5c as measured by an observer at rest in spaceship B.

Option B

Answer 2

Answer:

The value in frame S is 0.95c
