Consider the electrostatic force F on a test charge 'q' due to a uniformly charged spherical shell of radius R carrying total charge Q distributed uniformly over it. Which one of the following statements is true if 'q' is placed at a distance r from the centre of the shell?
- 1F ≠ 0 for r < R
- 2F is constant for all values of r
- 3F = 0 for r > R
- 4F = 0 for r < R✓
Correct answer
F = 0 for r < R
