Question

Three point charges are arranged in a horizontal line as shown below. Find the electric forces (in units of kQ2/R2) on the charges given the following: Q1 = -27 Q, Q2 = -36 Q, Q3 = 180 Q, r1 = 3 R, and r2 = 3 R. Remember that a positive force points to the right and a negative force points to the left.
