Q. Three nearly massless charges lie on a line. The charge of q1 is +5.4 , the charge of q2 is -2.9 , and the charge of q3 is 6.6 .

The distance A is found to be 0.38 meters. What is the distance B where charge q3 experiences no net force?

Q. A 0.100 kg meterstick is supported at its 40.0cm mark by a string attached to the ceiling. A 0.700 kg mass hangs vertically from the 5.00 cm mark. A mass is attached somewhere on the meterstick to keep it horizontal and in both rotational and translational equilibrium. If the force applied by the string attaching the meterstick to the ceiling is 19.6 N, determine the point where the mass attaches to the stick.
