Question

The figure shows the equipotential contours due to three point charges. The labels on the contours are in Volts. For each statement select T - True, F - False. The charge located at (0,0) is greater than the charge located at (-5,5). A charge released from rest on one of these contours will initially move along the contour. Two of the charges are negative and one is positive. The direction of the E-field at point e is along the tangent to the contour. The potential at a is greater than at b. -118.1 J of work is done to move a charge of 1 Coulomb from d to c along the contour. What is the magnitude of the potential difference between points e and a?

Explanation / Answer

A)True

B) False

they move perpendicular to contour

C) False

two are positive and is negetive

D) False

E-field is always perpendicular to contour

E) False

16.3>-357.9

F) False

they lie on same equipotential so work done =0

What is the magnitude of the potential difference between points e and a?

Ve-Va= 118.1- (-357.9)= 478 V
