Question

An object is doing uniform circular motion then there will be the
_________ angle between the vectors of its velocity when it is at
two ends of the diameter of the circular path

Anshu Agrawal · Accepted Answer

Dear student,
Velocity of particle describing uniform circular motion is
always perpendicular to the centripetal acceleration of the
particle as shown in the figure Tangential acceleration of the
particle is zero and thus centripetal acceleration is the only
acceleration of the particle which always acts towards the center
of the circular path
Thus angle between velocity and acceleration of the particle
describing uniform circular motion is 90o
