Solve the given problem:

Problem; Consider two point charges located on the x axis: one charge, q1 = -10.0nC, is located atx1 = -1.700m ; the second charge, q2 = 35.5nC ,is at the origin (x=0.0000).

Part A: What is the net force exerted by these two charges on a third chargeq3 = 46.0nC placed between q1 and q2 at x3 = -1.230m?

I need help to solve the above question and your answer may be positive or negative, depending on the direction of the force. Express your answer numerically in Newton's to three significant figures.
