Question

a pratical is moving on a circular path with constant speed, then the angle between the direction of acceleraton
and its position vector wrt centre of circle will be​

Answer 1

Explanation:

since speed is constant so only centripetal acceleration will be present and it will be parallel to position vector starting from centre of circle

hope it will help you,, and if correct mark it as brainliest

Answer 2

Answer:

π

Explanation:

suppose a particle travels in a circular path of radius r to a position P on the circle with the centre of the circle O as it's origin.

since the velocity is constant ,

therefore only centripetal acceleration acts.

centripetal acceleration acts from point P towards the centre O.i.e., in the direction exactly opposite to the position vector i.e.,r=OP nd centripetal acceleration=PO.

therefore the angle wrt the centre of the circle is π =180°
