Calculate the mutual force of repulsion between two charged spheres 2 cm apart of the repulsive force for a 1 cm separation is 16 n.

Force of repulsion is 4 N.

Explanation:

It is given that,

If separation between the charged sphere, r = 1 cm = 0.01 m

Force of repulsion, F = 16 N

We need to find the force of repulsion (F') when the separation between the spheres is r' = 2 cm = 0.02 m

The force of attraction or repulsion is given by :

i.e.

So,

F' = 4 N

So, the force of repulsion between the spheres is 4 N when the separation is 2 cm. Hence, this is the required solution.

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
