A particle P of mass m is attached to a vertical axis by two strings AP and BP of length l each. The separation AB=l. P rotates around the axis with an angular velocity `omega`. The tensions in the two strings are `T_(1) and T_(2)`

A

`T_(1)=T_(2)`

B

`T_(1)+T_(2)=momega^(2)l`

C

`T_(1)-T_(2)=2mg`

D

BP will remain taut only if `omega ge sqrt((2g)/(l))`
