Question
6. With V- at infinity, find the electric potential at point P an at = d. a) 0 b) R In (d) c) (In(d + L)-ln (d)) d) 4meln(d + L) e) -In(1-d) 17. With V- 0 at infinity, find the electric potential at point Pa at y D. a) 0 on the y axis b) ARe in (D) c) (ln((d? + L2)1/2 + 1)-In (D)) d) In(a+1)+L) IV The figure shows three pairs of parallel plates with the same separation. plates The electric field between the plates is uniform and perpendicular to the . -900 V -400 V -20V +200 V -50 V +150 V 18. For which pair is the electric field pointing leftward? b) 2 d) 1 and2 e) 2 and 3 19. If an electron is released midway between the first pair of plates a) it will remain there b) move rightward at constant speed c) move leftward at constant speed d) accelerate rightward e) accelerate leftwardExplanation / Answer
(18) The field points to the left for the options 1 and 2. Hence, the correct option is (d).
(19) The electron would accelerate towards the right. Hence, the correct option is (d).
