Explanation:
It is given that,
Let q₁ and q₂ are two small positively charged spheres such that,
.............(1)
Force of repulsion between the spheres, F = 1 N
Distance between spheres, d = 2 m
We need to find the charge on the sphere with the smaller charge. The force is given by :
............(2)
On solving the system of equation (1) and (2) using graph we get,
So, the charge on the smaller sphere is 11.6 micro coulombs. Hence, this is the required solution.
