Question

If two charged bodies experience a repulsive force of 0.2 N, then on doubling both the charges without changing the distance between them the new force will become

a 0.10 N

b 0.40 N

c 0.05 N

D 0.80 N

Answer 1

If two charged bodies experience a repulsive force of 0.2 N, then on doubling both the charges without changing the distance between them the new force will become 2 * 2 * 0.2 N = 0.8 N.
