Electric Field Problem

  1. Mar 1, 2012 #1
    1. The problem statement, all variables and given/known data
    A proton near the surface of the earth is in equilibrium under the force of gravity and the force of an electric field. What electric field is required?


    2. Relevant equations
    m(proton)=1.67x10-27


    3. The attempt at a solution
    I found the force of gravity on the proton which is F=1.63^26 by multiplying the proton with the acceleration of earth F=ma
    I don't know how to find the electric field. I try using the formula E=F/Q, the Q being 1.6x1019.

    Problem is here

    OH NVM I GOT IT XD
