1. The problem statement, all variables and given/known data
A Van de Graaff generator is charged so that the electric field exerted at the top surface is 2.0× 10^6 N/C directed upwards. Find the a) the electric force exerted on a styrofoam peanut (q= 0.025μC) released at its surface, b) the gravitational force on the peanut, c) its acceleration
(g= 10 m/s^2 & mass of peanut=0.20g)
2. Relevant equations
