Please help! Questions about Electricity and Work

  1. Nov 10, 2011 #1
    1. What is the electric field magnitude midway between charges of Q1 = 2 C and Q2 = 9 C separated by 2 m?


    2. How much work does a 9 V battery do in pushing 9 mC of charge through a circuit containing one lightbulb?


    3. Points A and B each have an electric potential of +3 V. How much work is required to take 1 mC of charge from A to B?

    1. The problem statement, all variables and given/known data



    2. Relevant equations



    3. The attempt at a solution

    Hi Fluffy22,
    you need to show some effort at solving the problems before help can be given; otherwise how will we know how to help? We don't do your homework for you here!
