A body moves in a circular path of radius R with deceleration so that at any moment of time its tangential and normal acceleration are equal in magnitude. At the initial moment t = 0, the velocity of body is v 0 then the velocity of body at any time will be –
A
v = 
at time t
at time t
B
v = 
after it has moved S meter
after it has moved S meter
C
v = v 0 e –SR after it has moved S meter
D
None of these
