In circular motion

Options

A. radial acceleration is non-zero
B. radia velocity is zero
C. body is in equallibrium
D. All of the above

Explanation

(d) In cicrular motion rdial aceleration `a_(1)=(v^(2))/(r)` and the particle does not move along the radius of he circular path hence radial velocity is zero radial acceleration only changes the direction of motion of the particle .
