A block of mass m=5kg is being whirled in a horizontal circle with the help of a string of length l=1m with constant speed v=`5ms^(-1)`. One end of the string is held fixed at a point O above the centre of the horizontal circle Gravity exists vertically downwards. the force of tension exerted by the string on bob is `vecT`. For this given situation. Choose INCORRECT statement.

A

Total force acting on mass is `mvecg+vecT-(mv^(2))/(l)vecT`

B

Total force acting on mass is `mvecg+vecT`

C

Net force on the particle is in the horizontal direction

D

horizontal component of tension provides required centripetal force.
