Which one of the following is false: a) a body can have zero velocity and still be accelerated. b) a body can have constant velocity and still be accelerated .

c) the direction of the velocity of a body can change when its acceleration is constant

d)a body can have constant speed and still have varying velocity

Explanation:

Speed is a scalar quantity that only number and velocity is a vector which means having magnitude and direction both. In order to have constant velocity the speed needs to be constant. Whereas a body can have constant speed with changing direction (velocity).

When car going roundabout is the perfect example of this situation. 

it will be pushed away from the source of the electric field. a negative charge in a cloud induces a positive charge in the ground below the cloud.
