# Charges in Right Triangle

Three equal charges are placed in such a way that they form a right triangle with sides 3 cm, 4 cm and 5 cm. Each charge has a magnitude of $$2\times 10^{-6}\text{C}$$.

Find the net force acting on the charge at the right angle.

Details and assumptions:

• Take $$\dfrac 1{4\pi\epsilon_0} = 9\times 10^9\frac{\text{Nm}^2}{\text{C}^2}$$.
