Question

Two identical conducting spheres (charges Q and −Q) touch and separate. Force between them after separation compared to before:
  1. A
    Same
  2. B
    Zero
    Correct
  3. C
    Larger
  4. D
    Smaller

Correct answer

Zero

Explanation

When they touch, charge redistributes: equal and opposite charges neutralise. Total charge = 0. Each sphere gets 0 charge → force = 0.
