A Carnot engine's operating temperatures are 210 degrees Celsius and 45 degrees Celsius. The engine's power output is 950 W. Calculate the rate of heat output.

Q1 = 6.0 nC is at (0.30 m, 0); Q2 = -1.0 nC is at (0, 0.10 m); Q3 = 5.0 nC is at (0, 0). What is the magnitude of the net force on the 5.0 nC charge? I'm not sure how to start this problem.. what equation should I use?
