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 27 KV that repels paint droplets onto a grounded wall. Note that the charge on the paint sphere sprayer is not the same as the charge on the paint droplets. (a) What charge is on the sphere? Qsphere C 9 drop paint drop repelled to the wall Vsphere C Vwall=0 m (b) What charge must a 0.08 mg drop of paint have to arrive at the object with a speed of 10 S Electrostatic Paint Sprayer -?
