Question #159835

Two identical charges of 5nc repel each other when they are 5 cm apart from each other. find out the magnitude of force b/w them.

Expert's answer

"F=\\dfrac{kq_1q_2}{r^2},""F=\\dfrac{9\\cdot10^9\\ \\dfrac{Nm^2}{C^2}\\cdot(5\\cdot10^{-9}\\ C)^2}{(0.05\\ m)^2}=9.0\\cdot10^{-5}\\ N."
