What must the charge (sign and magnitude of a particle of mass 1.48 g be for it to remain stationary when placed in a downward-directed electric field of magnitude 640 n/c? use 9.81 m/s2 for the magnitude of the acceleration due to gravity?

shows two blocks connected by a cord (of negligible mass) that passes over a frictionless pulley (also of negligible mass). The arrangement is known as Atwood's machine. One block has mass m1 = 1.30 kg; the other has mass m2 = 2.80 kg.
