Compute all parts of given question:
Question: A point charge Q=+ 4.50uC is held fixed at the origin. A second point charge q=+ 1.30uC with mass of 2.10 x 10-4 kg is placed on the x-axis, 0.220m from the origin.
Part I: What is the electric potential energy U of the pair of charges? (Take U to be zero when the charges have infinite separation.)
Part II: The second point charge is released from rest. What is its speed when its distance from the origin is 0.440m?
Part III: The second point charge is released from rest. What is its speed when its distance from the origin is 4.40m?
Part IV: The second point charge is released from rest. What is its speed when its distance from the origin is 44.0m?
I am not able to get the correct answer please help me. Thanks.
