Solution Summary

This solution calculates the magnitude and direction of the electric field that can balance weights of electrons and protons.

Solution Preview

To balance the weight of an charged particle by an electrical field, we can derive the equation as

mg=qE

where m is the mass of the particle and q is the amount of ...
