Explanation / Answer
a) Suppose the black dot located along the 200-v potential line represents a particle with a charge of +0.2C. If the particle is released from rest, would the particle move to the right or to the left? explain A positive charge will move to lower potential place, so it would move to the left. b)a) Suppose the black dot located along the 200-v potential line represents a particle with a charge of -0.2C. If the particle is released from rest, would the particle move to the right or to the left? explain A negative charge will move to highwer potential place, so it would move to the right. C) a) Suppose the black dot located along the 200-v potential line represents a particle with a charge of +0.2C moving toward right with a kinetic energy of 100J. What would the particle's kinetic energy be when it reaches the 350V line? initial energy = 100 + 0.2*200 = 140 J final energy = K + 0.2*350 = K + 70 J 140 = K + 70 K = 70 J d) Suppose the black dot located along the 200-v potential line represents a particle with a charge of -0.2C moving toward right with a kinetic energy of 100J. What would the particle's kinetic energy be when it reaches the 350V line? initial energy = 100 + (-0.2)*200 = 60 J final energy = K + (-0.2)*350 = K - 70 J 60 = K - 70 K = 130 J
