A particle is moving on a circular path in xy-plane with centre at the origin. At t=0, it is (1,0). It has a constant angular velocity of `(pi)/4` rad/s in clockwise direction

`{:("Column-I",,"Column-II"),("(A) has +ve x as well as +ve y-component.",,"(P) Acceleration at t=1 sec"),("(B) has -ve x as well as -ve y-component",,"(Q) Velocity at t=1 sec"),("(C) has -ve x but +ve y-component",,"(R) Position at t=1 sec"),("(D) has +ve x but -ve y-component",,"(S) Acceleration at t=3 sec"),(,,"(T) Velocity at t=3 sec"):}`

Answer

R
S
P
T

Explanation

`theta =wt =(pi)/4 " " q'=omegat=(3pi)/4`
at t=1 sec.
