A uniform circular ring of mass m and radius R is placed freely on a horizontal smooth surface as shown in figure. A particle of mass m is connected to the circumference of the ring with massless string . The particle is imparted velocity `v_0` perpendicular to length of string as shown. If T is tension in the string just after the particle imparted velocity , then

Acceleration of point P at this instant , is

`(4T)/(3m)`

`T/m`
