1) A particle of mass 46 g and charge 69 muC is released from rest when it is 52 cm form a second particle of charge -20 muC.
Determine the magnitude of the initial acceleration of the 46 g particle. Answer in units of m/s^2
2) An object having a net charge of 33.8 muC is placed in a uniform electric field of 271 N/C directed vertically up. The acceleration of gravity is 9.8 m/s^2. What is the mass of this object if it "floats" in the field?
