Question

Consider the arrangement of two fixed point charges, equal in magnitude, shown in the figure. Which of the following statements are correct for the initial motion of a third charge if it is released from rest in the vicinity of the two charges shown?

True False A positive charge at point d will accelerate up.
True False  A negative charge at point e will accelerate up.
True False  A negative charge at point b will accelerate down.
True False  A positive charge at point c will accelerate toward the lower-left.
True False  A negative charge at point a will accelerate toward the lower-right.

Explanation / Answer

(a). False -- A positive charge at point d will accelerate up.
True ---- A negative charge at point e will accelerate up.
True ----- A negative charge at point b will accelerate down.
False --- A positive charge at point c will accelerate toward the lower-left.
False ---- A negative charge at point a will accelerate toward the lower-right
