<p>I'm in Physics B and need help on the following problem (it deals with Electric Potential Energy)....</p>
<p>A 4.00 kg block is connected to a spring k = 100 N/m. The block is charged Q = 50.0 (mu)C. The block is on a frictionless track, and the system is immersed in a uniform electric field of magnitude E = 5.00 x 105 V/m. Find: (a) the max amount the spring stretches, if the block is released at rest when the spring is unstretched, (b) equilibrium position of the block.</p>
<p>Anyone?</p>
