Apoint charge q is located a distance d away from the center of a very long charged wire. the wire has length l > > d and total charge q. what force does the wire experience?

Explanation:

As we know that if a charge q is distributed uniformly on the line then its linear charge density is given by

now the electric field due to long line charge at a distance d from it is given as

now the force on the other charge in this electric field is given as

true, as the earth rotates the sun hits the surface of the planet; causing the day and night cycle.

the answer is to check all of them! they all apply well at least i think so!
