Question

Consider the arrangement of two fixed point charges, equal in magnitude, shown in the figure. Which of the following statements arc correct for the initial motion of a third charge if it is released from rest in the vicinity of the two charges shown? A positive charge at point d will accelerate up. A positive charge at point b will accelerate up. A negative charge at point c will accelerate up. A positive charge at point a will accelerate toward the lower-left. A negative charge at point c will accelerate toward the lower-right. Tries 0/20

Explanation / Answer

A is false; a positive charge at point d will be attracted to the nearby negative more than it is repelled by the more distance positive.

B is true

C is true

D is false; the dipole field at point a is directed up (it curves from the lower positive charge to the upper negative one, but is directly upward here) so the charge will initially accelerate up

E is false; similar to question D, the field is up at point c so the negative charge will accelerate initially straight down.
