Question
What is the direction of the centripetal force w.r.t. the centripetal acceleration?
- Perpendicular to the centripetal acceleration
- Parallel to the centripetal acceleration
- At an angle of 30 degrees to the centripetal acceleration
- At an angle of 60 degrees to the centripetal acceleration
Hint:
The centripetal force acts towards the centre.
The correct answer is: Parallel to the centripetal acceleration
Here the correct option will be 'b' i.e; parallel to the centripetal acceleration. It is because a body moving in a circular motion requires centripetal force which acts inwards towards the centre of the circle. The body is also accelerated in the same direction so that it can continue its circular motion.
