Question #155642

Determine the magnitude and direction of the electromagnetic force between the two charges 66 and -22 separated by the distance 45.

Expert's answer

"F=k\\frac{q_1q_2}{r^2}\\\\\nF=9\\cdot10^9\\frac{(66)(-22)}{(45)^2}=-6.45\\cdot10^9N"

Negative sign means that the force is attractive.
