Matt forgot to put the fabric softener in the wash. as his socks tumbled in the dryer, they became charged. if a small piece of lint with a charge of +1.25 e -19 c is attracted to the socks by a force of 3.0 e -9 n, what is the magnitude of the electric field at this location?

Explanation:

The electric force exerted on a charge due to an electric field is given by:

where

q is the magnitude of the charge

F is the magnitude of the force

E is the magnitude of the electric field

In this problem, we have:

is the charge

is the magnitude of the force

using these data and re-arranging the equation, we can calculate the magnitude of the electric field:

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

the answer is a)
