Question
What is the angle between the velocity vector and the centripetal force?
- 0 degree
- Less than 90 degrees
- 90 degrees
- More than 90 degrees
Hint:
In a uniform circular motion, velocity is along tangential direction and acceleration is always towards centre
The correct answer is: 90 degrees
In a uniform circular motion, velocity is along tangential direction and acceleration is always towards centre, so angle between velocity vector and acceleration vector is always π/2.or 90
