Answer:
(B) The speed is larger at A than at B.
Explanation:
Point B, the final point of the trajectory, has higher electric potential than point A, the initial point of the trajectory, so the electric potential energy of the charged particle increases, which means that its kinetic energy must be decreasing, thus the speed at B must be lower than the speed at A.

Answer:
Explanation:
During a course of elliptical motion the direction of the body keeps changing however its magnitude may or may not remain constant.
During a curve path motion the velocity of the object is directed in a tangential direction to the curve.
During the motion on a curved path if the magnitude of a body remains constant then the body is said to have a constant speed which is a scalar quantity. Scalar quantities do not have direction.
