A negative point charge - Q is at the center of a hollow insulating spherical shell, which has an inner radius R 1 and an outer radius R 2 . There is a total charge of +4 Q spread uniformly throughout the volume of the insulating shell, not just on its surface. Determine the electric field for the following. (Use any variable or symbol stated above along with the following as necessary: r and ε 0 .)

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

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

what is the actual question though?
