Answer 1

Answer:

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 a massless string. The particle is imparted velocity v 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 iñstant , is
