Question

3.[1pt] The diagram shows equipotential contours around three point charges, 1., and Q3 Values of the potential are given in kilovolts; the interval between contours is 1 kV. Four locations on the contours have been labeled, a d 2. -5 cm 1 Select all the correct statements, e.g., AB. If none of the statements is correct, enter N A. The electric potential at point d is equal to the potential at point c. B. 03 is a positive charge. C. The electric potential at point b is zero D. The electric field at point a points up. E. The electrie field at point b is zero. F. An electron placed at point c will accelerate to the left.

Explanation / Answer

(A) The potential of d is 1 kV while for c, its 2 kV. hence false statement

(B) The potential for a positive charge is positive hence statement is true

(C) True as it lies on equipotential curve have zero potential

(D) False. The field is directed from higher to lower potential hence it must be in the downward direction as in downward direction, the potential is low

(E) False, There is non zero slope at point b hence there must be electric field.

(F) False. As electron has negative charge hence it will move towards right, towards positive charge or high potential
