The answer to the question above is letter D. The separation of positive and negative charges due to electric field is called an induced charge. It is a movement of electrons in a substance caused by the electric field of a nearby charged object.
(distance covered) divided by (time to cover the distance) is SPEED.
(straight-line distance and direction between start-point and end-point) is DISPLACEMENT.
(amount and direction of change in speed) divided by (time for the change) is ACCELERATION.
(amount and direction of change in momentum) divided by (time for the change) OR (mass) times (acceleration) is FORCE.
