Question

The diagram shows the E field lines (with arrows) and the equipotential contours for a certain charge configuration. Select T-True or F-False for the following statements. If the first is true and the rest false, enter TFFF.

A)The equipotential and field lines shown could represent those of a negative point charge.

B)A dipole with centre at C and free to rotate about C will rotate such that the positive pole swings towards B.

C)An electron placed at B will move towards A.

D)The E-Field at B is stronger than at C.

Explanation / Answer

FTTF

A) No, Positive field lines are moving outward.

B) Yes, due to torque on dipole.

C) Yes, Potetial at A is more than potential at B

D) No, Electric field lines at B are very from other, so electric filed is less at B
