PHYS 202 Midterm: PHYS 202 TAMU s11 Exam 1 Solutions
Document Summary
No work need be shown and no partial credit will be given. (5 pts) 1. A negative point charge with q = 5. 0 x i0 c is placed at a point where the electric field is in the x direction. What is the direction of the force that the electric field exerts on the point charge? (c) y (d) +y (5 pts) 2. A parallel plate capacitor has charge q on its plates. The capacitor is not connected to a battery. so the charge on the plates can"t change. If the plates are pulled apart, so the separation between the plates increases, the potential difference between the plates (a) stays the same (b) decreases (ncrease) A hollow spherical shell with radius r = 0. 6 in has charge q = 2 x i0 c distributed uniformly over its surface. N/c and that is in the x-direction. potential at x.
