1547220564 (5 of 505) d 41. As shown in the diagram above, a charged particle having mass m and charge -q is projected into the region between two parallel plates with a speed v, to the right. The potential difference between the plates is V and they are separated by a distance d. What is the net change in kinetic energy of the particle during the time it takes the particle to traverse the distance d? (A) + ; muo? (B)-aVId (C) TO% (D) +9V (E) None of tho above 2d ¡0- 42. Two conducting spheres, one having twice the diameter of the other, are shown above. The smaller sphere initially has a charge +q. When the spheres are connected by a thin wire, which of the following is true? (A) 1 and 2 are both at the same potential. (B) 2 has twice the potential of 1. (C) 2 has half the potential of 1. (D) 1 and 2 have equal charges. (E) All of the charge is dissipated.
