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
qwelly [4]

Answer:

2.4\cdot 10^{10}N

Explanation:

When an electric charge is immersed in an electric field, it experiences a force given by the equation

F=qE

where

q is the charge

E is the magnitude of the electric field

In this problem, we have:

q=+1.25\cdot 10^{-19}C is the charge on the small piece of lint

F=3.0\cdot 10^{-9}N is the force experienced by the  charge

Therefore, we can find the magnitude of the electric field by re-arranging the equation and solving for E:

E=\frac{F}{q}=\frac{3.0\cdot 10^{-9}}{1.25\cdot 10^{-19}}=2.4\cdot 10^{10}N
