Question
Part A Part B Express your answer in joules.Part C The magnitude of the electric field at pointC is
greater than the magnitude of the electricfield at point B.
less than the magnitude of the electric fieldat point B.
equal to the magnitude of the electric field atpoint B.
unknown because the value of the electricpotential at point C is unknown.
Part C The magnitude of the electric field at pointC is

less than the magnitude of the electric fieldat point B.
equal to the magnitude of the electric field atpoint B.
unknown because the value of the electricpotential at point C is unknown.
Explanation / Answer
a) Since the potential difference between the beginning pointand the end point is the same, no work is done. b) There is a potential drop of 1 V = 1 J/C, so the work doneis -1 Joule. c) The electric field is greater at C since the equipotentialsurfaces are closer to together there. Since E is thenegative of the gradient of the potential, the more quickly Vchanges, the larger the value of E.
