y x Problem 1: Three point charges Q1 = 1 uc, Q2 = 2 uC and Q3 = 3 uC are fixed in the (x, y) plane at the points (0.0, 0.0), (0.0, 3.0) and (4.0, 0.0) m, Q2 (0,3m) P(4m,3m) respectively, as shown in the diagram below. The point P is at (4.0, 3.0) m. a) What is the electric field at the point P? b) What is the electrostatic potential at Q:(0,0) Q3 (4m, 0) the point P? c) What is the electrostatic potential energy of the system of these three charges? d) A proton is released from rest at point P. What is its initial acceleration? e) As in question d) above, a proton is released from rest at point P. What is its final speed when it's very far from the system of charges Q1, Q2 and Q3? f) How much work is done by the electric field to move an electron from infinitely far away to point P?
