Question

I need someone to solve problem 4&5 with steps. 4. Compute the work required to bring the following three charges from rest at an infinite separation to the following (x, y) locations: q1 = +6.00 muC at (0.0, 0.0) m, q2 = 3.00 muC at (1.5, 0.0) m, and q3 = +4.00 muC at (1.5, 5.0) m. Assume the charges are initially at rest and separated by an infinite distance. 5. After the charges in problem 4 are assembled the 6.00 muC charge is released from rest. What is its kinetic energy when it is infinitely far from the other two charges?

Explanation / Answer

4. The data are insufficient to correctly answer the problem. In general, the work required to move a charge q, IN THE ELECTRIC FIELD GENERATED BY ANOTHER CHARGE Q, from a position A to a position B is give by

W = (1/4po epsilon0) Qq (1/rA - 1/rB). In this case, rA = infty for all, and rB can be calculated as rb = sqrt(x^2 + y^2). The problem is the charge Q generating the external field is missing

5. In virtue of the conservation of total energy, the kinetic energy hold by the charge at infinity, where its potential energy is nil, is equal to the potential energy at the beginning, when its kinetic energy is nil. Thus, one must calculate the potential energy.
