Question

Four point charges q = 2 C, Q B = -5 C, Q = 2 C, Q = 5 C are located at the corners of a square ABCD of side of 10 cm. What is the force on a charge of 1 C placed at the centre of the square​

Answer 1

Answer:

1.8×10^9

Explanation:

2C s are in opposite corners of square. so,their forces canceled each other. and the rest

one attractive and other repulsive..and along one direction.

so,F= 2×(1/4 pi Eo)(1×5/25×2)

= (2×9×10^9×5)/50

=1.8×10^9
