A heavy particle is tied ot the end A of a string of length `1.6m`. Its other end `O` is fixed. It revolves as a conical pendulum with the string making `60^(@)` with the vertical. Then `(g=10m//s^(2))`

A

its period of revolution is `(4pi)/(7)` sec.

B

the tension in the string is double the weight of the particle

C
