Q. A weight lifter lifts a set of weights the vertical distance of 1.56m. If A constant net force of 379N Is exerted on the weights, what's the net work done on the weights?
Q. A charge of -3.55 nC and a charge of -5.65 nC are unconnected by a distance of 60.0 cm. Find the position at which a third charge of +7.20 nC can be located so that the net electrostatic force on it is zero.
