Two identical conducting small spheres are placed with their centers 0.290 m apart. one is given a charge of 12.0 nc and the other a charge of -21.0 nc. find the electric force exerted by one sphere on the other.

Force between two identical conducting ball will be                        

Explanation:

We have given there is two identical conducting small spheres having charge and

Distance between centers of the ball is 0.290 m

So r = 0.290 m

We have to fond the electric force between the balls

According to Coulomb's law force between two charges is given by

So force

So force between two identical conducting ball will be

heats surface water up

answer is slate
