1. An eletrostatic paint sprayer consists of a charged metal sphere. Charged paint droplets (the sign the same as the metal sphere) are shot towards the metal sphere using a paint gun. The paint droplets repel and move towards a grounded object that needs to be painted. In the figure below, an electrostatic paint sprayer has a 0.2 m diameter metal sphere at a potential V of 20 kV that repels paint droplets onto a grounded wall. sphere Vwall=0 (a) What charge is on the sphere? Qsphere 0 C = paint drop repelled to the wall Vsphere Electrostatic Paint Sprayer
