Q. A charge of -3.60 nC and a charge of -5.30 nC are separated by a distance of 40.0 cm. Find out the position at which a third charge of +7.40 nC can be positioned so that the net electrostatic force on it is zero.

Q. A 1200 kg car moving north at 27 m/s is struck by a 2165 kg car moving east at 11.0 m/s. The cars are stuck together. How fast and in what direction do they move at once after the collision?
