Van de Graaff & electric force?

Click For Summary
SUMMARY

The discussion centers on calculating the electric force exerted on a styrofoam peanut by a Van de Graaff generator with an electric field strength of 2.0×10^6 N/C. The electric force on the peanut, which has a charge of 0.025μC, is determined using the formula F = qE, resulting in a force of 50 N directed upwards. Additionally, the gravitational force acting on the peanut, with a mass of 0.20g, is calculated to be 0.002 N downwards. The net acceleration of the peanut is derived from the net force acting on it.

PREREQUISITES

Homework Statement


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)
