A metal sphere hangs from a string and has 4 kg of mass. The sphere has a charge of +3.5 pc. A uniform electric field is turned on and directed to the right. (a) Which way does the sphere move? left right (b) What is the electric force on the metal sphere ifr the magnitude of the electric field is 10 N/C? (c) When the sphere reaches equilibrium, what is the angle that the string makes with the vertical axis (assuming the same electric field as part (b))?
