Question

Two charges of 4 microcoulomb exerts a force of 40 Newton on each other find the distance between them ?

Answer 1

Answer:

The distance between them is 5.99 m

Explanation:

According to the problem the both the particles have the charge of 4 micro coulomb

Let q1 and q2 be the charges of the particle

Then q1 and q2 = 4 micro coulomb

Let force = F

here both the particle exert 40 N of force

we know,

F =k x q1 x q1 / r^2

where r is the distance

40 = 9 x 10^9 x 4 x 4 / r^2

r = 5.99 (approximate)
