# Two insulated charged copper spheres A and B have their centers separated by a distance of 50 cm. What is the mutual force of electrostatic repulsion if the charge on each is $6.5 \times 10^{−7}\; C?$ The radii of A and B are negligible compared to the distance of separation.

## 1 Answer

$1.5 \times 10^{-2} N$
Hence A is the correct answer.
