Circular MotionMedium
Question
Let ar and at represent radial and tangential acceleration. The motion of a particle may be circular if :
Options
A.ar = 0, at = 0
B.ar = 0, at ≠ 0
C.ar ≠ 0, at = 0
D.none of these
Solution
For circular motion of particle ar not equal to zero, at may or may not be zero (ar = v2 / r)
