Questions 1-2 1. If the magnitude of the electric field at point X is E, what is the magnitude of the electric field at point Y? Y (A) E/4 X 2 (B) E/2 (C) E (D) 2E (E) 4E 2. A positive point charge to is released from rest Note: Figure not drawn to scale. at point X. If the magnitude of the electric field at point X is E, what is the kinetic energy of the charge at point Y? The figure above shows a thin, square, nonconducting sheet of positive charge uniformly (A) qEd distributed over its area. The length of each side of (B) 2qEd the sheet is a. Point C is at the center of the sheet. Point X is a distance d above the center of the sheet, (C) 2qEd and point Y is a distance 2d above the center of the (D) 2 2qEd sheet. Assume a > > d. The effect of gravity is (E) 4qEd negligible
