Question
The figure shows the equipotential contours due to three point charges, labelled in volts.
Select T-True, F-False for each of the statements below. E.g., if the first is true and the rest false, enter TFFFF.
A The direction of the electric field at e is along the tangent to the contour.
B A charge released from rest on one of these contours will not move along the contour.
C -118.1 J of work is done to move a charge of 1 coulomb from d to c along the contour.
D Two of the charges are negative and one is positive.
E The charge located at (0,0) is greater than the charge located at (-5,5).
F The potential at b is greater than the potential at a.
