Question:

Choose the correct alternative.

Options:

The acceleration of a moving particle is always in the direction of its velocity

Velocity and acceleration vectors of a moving particle may have any angle between 0 and 360 between them

Velocity and acceleration vectors of a moving particle may have any angle between 0 and 180 between them

If the acceleration vector is always perpendicular to the velocity vector of a moving particle, the velocity vector does not change

Correct Answer:

Velocity and acceleration vectors of a moving particle may have any angle between 0 and 180 between them

Explanation:

In circular motion, acceleration vector is perpendicular to velocity and velocity is also changing. Now acceleration and velocity can have any angle between them.
Hence (c) is the correct answer.
