A heavy particle is tied to the end A of a string of length 1.6 m. Its other end O is fixed. It revolves as a conical pendulum with the string making `60^(@)` with the vertical. Then (take `g = 9.8 m//s`)

A

Its period revolution is `(4pi)/(7) ` sec

B

The tension in the string is doubled the weight of the particle

C

The speed of the particle = `2.8 sqrt(3) m//s`

D

The centripetal acceleration of the particle is `9.8 m//s^(2)`
