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

Explanation / Answer

1) this is true , the electric field is pointing downwards

2)this is false , the net force at the negative charge will be downwards

3)this is false , the net force on the charge will be upwards

4)this is false , the net force at the negative charge will be downwards

5) this is true.
