Van de Graaff & electric force?

  1. Apr 22, 2008 #1
    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



    3. The attempt at a solution
