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 =-6 Q, Q2 = -4 Q, Q3 = -6 Q, r1 = 1 R, and r2 = 1 R. Remember that a positive force points to the right and a negative force points to the left.

What is the net force on charge Q1?

What is the net force on charge Q2?

What is the net force on charge Q3?

What is the sum of the forces on all three charges?
