A body is travelling with a constant speed on the circumference of a circle. Of the quantities : acceleration towards the centre.

When a body moves with a constant speed along a circle

If a body moves with a constant speed in a circle

A particle is moving with speed v= 2t^(2) on the circumference of a circle of radius R. Match the quantities given in Table-1 with corresponding results in Table-2 {:(,"Table-1",,"Table-2"),("(A)","Magnitude to tangential acceleration of particle","(P)","decreases with time"),("(B)","Magnitude of centripetal acceleration of particle","(Q)","increases with time"),("(C)","Magnitude of angular speed of particle with respect to centre of circle","(R)","remains constant"),("(D)","Angle between the total acceleration and centripetal acceleration of partilce","(S)","depends upon the value of radius R"):}

If the kinetic energy of a particle moving with a constant speed on a circular path of radius 4 m is 100 j .Then the centripetal force will be
