Comparing Electric Fields

APPH12-BGN5EH

The electric field at point $A$ is $10$ $N/C$ to the right and the electric field at point $B$ is $50$ $N/C$ to the left.

Ignoring any other fields, which of the following must be TRUE?

Select TWO answers.

A

The charge at point $B$ is $5$ times the charge at point $A$.

B

The magnitude of the electric force on a positively charged, $+ 2$ $C$ object placed at point $A$ is $20$ $N$.

C

The direction of the acceleration of a positively charged, $+2$ $C$ object placed at point $A$ is to the right.

D

The magnitude of the acceleration of a negatively charged, $-2$ $C$ object placed at point $B$ is $100$ $m/s/s$.
