Question

The net electric force on a charge of +3 μ C at the mid-point on the line joining two charges of magnitude +2 μ C and -2 μ C separated by the distance of 6 mm, is (A) 6000 N (B) 500 N (C) 60 N (D) zero

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

Q. The net electric force on a charge of $+ 3 μ C$ at the mid-point on the line joining two charges of magnitude $+ 2 μ C$ and $- 2 μ C$ separated by the distance of $6 mm,$ is

6000 N

500 N

60 N

zero

From Coulomb's law Force due-to same charge is repulsive and that due to opposite is attractive.
$F = K [\frac{2 \times 3}{3 ^{2}} - \frac{2 \times 3}{3 ^{2}}] = 0$
