The net electric force on a charge of +3μC at the mid-point on the line joining two charges of magnitude +2μC and -2μC seperated by the same distance of 6mm, is
Options
(a) 6000N
(b) 500N
(c) 60N
(d) zero
Correct Answer:
zero
Explanation:
From Coulomb’s law, force due to same charge is repulsive and that due to opposite is attractive.
F = K [(2×3/3²) – (2×3/3²)] = 0
