The upper end of the string of a simple ...


The upper end of the string of a simple pendulum is fixed to a vertical z-axis and set in motion such that the bob moves along a horizontal circular path of radius 2 m. parallel to the xy plane, 5 m above te origin. The bob has a speed of `3m//s`. the string breaks when the bob is vertically above the x-axis and it lands on the xy plane at a point (x,y)

A

`x=2m`

B

`xge2m`

C

`y=3m`

D

`y=5m`
