Problem 7: An electrostatic paint sprayer has a 0.15 In diameter metal sphere at a potential of 25.0 kV With respect to the ground that repels paint droplets onto a grounded object. Part (a) What charge is on the sphere, in coulombs? Numeric __; A numeric value is expected and not an expression. Q: Part (b) What charge, in coulombs, must a 0.075 mg drop of paint have in_9r_d_e1_'_t_q arrive at the object With a speed of 10.0 m/s, starting from rest? Numeric __'. A numeric value is expected and not an expression
