A bob is released from the horizontal position of the inextensible string. If the breaking strength of the string is equal to twice the weight of the bob. Find the.
(A) Position where the string breaks.
(B) Time after which the bob strikes the ground measured from the instant of breaking of the sting.
(C ) Displacement of the bob from its point of breaking to the point of striking.

`(A)theta=cos^(-1)((2)/(3))`from the vertical
(B) `t=sqrt((20R)/(27g)+(16R)/(6g))-sqrt((20R)/(27g))`
`(C) (4l)/(3)sqrt((4)/(81)(sqrt23-sqrt5)^(2)+1)`
