Question #317987

The force in the middle of two identical charges separated by 1.77 cm is equal to 70N. What is the magnitude of the two forces?

Expert's answer

The Coulomb's law says

"F=k\\frac{|q_1||q_2|}{r^2}"

The magnitude of charges

"q=\\sqrt{\\frac{Fr^2}{k}}=\\sqrt{\\frac{70*0.0177}{9*10^9}}=1.17*10^{-5}\\:\\rm C"
