Answer:
option B
Explanation:
we know,
Force between two charge is calculated by
r is the distance between the two charges
k is Coulomb constant.
give two small object with charge Q
now, Force
......(1)
now,
New force if another charge is equal to 4 Q
now from equation 1
Hence, the correct answer is option B
