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

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.
