A ball tied to the end of the string swings in a verticla plane in a vertical circle under the influence of gravity.

A

When the string makes an angle `90^(@)` with the vertical, the tangential acceleration is zero and radial acceleration is somewhere between minimum and maximum.

B

When the string makes an angle `90^(@)` with the vertical , the tangential acceleration is maximum and radial acceleration is somewhere between maximum and minimum.

C

At no plae in circular motion, tangential acceleration is equal to radial acceleration `(` in magnitude `)`

D

When radial acceleration has its maximum value, the tangential acceleration is zero.
