A wrecking yard inventor wants to pick up cars by charging a 0.400 m diameter ball and inducing an equal and opposite charge on the car. If a car has a 1000 kg mass and the ball is to be able to lift it from a distance of 1.00 m:

(a) What minimum charge must be used?

(b) What is the electric field near the surface of the ball?

(d) Which premise or assumption is responsible?
