The electrostatic force between two charged spheres is 64 n. what will the magnitude of the force be if the size of each charge is doubled and the distance between the spheres is doubled?

The magnitude of the force if the size of each charge is doubled and the distance between the spheres is doubled is 64 newtons.

Explanation:

The magnitude of electrostatic force between two charged objects is:

With and the charges and r the distance between the charges (in our case the distance between the spheres).At first we have that the force is 64N so:

(1)

Now if each charge is doubled and the distance between them is doubled too:

, Note that it's the same on the right side equation (1) so

Magnitude of the force is the same!

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
