Question

A particle is moving in uniform circular motion in x-y plane, with radius 1m and centre as origin. At t = 0, the particle is (R, 0) as shown. Time period of the path is 4 seconds. Match the quantities the of column-I with possible instant of time(s) of column-II.

Column-I	Column-II
	(P) till t = 1 sec.
	(Q)till t = 3 sec.
(C) Distance travelled by the particle is $\frac{πR}{2}$	(R) till t = 5 sec.
(D) Magnitude of displacement of the particle is $R \sqrt{2}$	(S) till t = 7 sec.
	(T) till t = 9 sec.

(A) As average acceleration ${\vec{a}}_{avg .} = \frac{{\vec{V}}_{f} - {\vec{V}}_{i}}{Δt}$
(B) As direction of average velocity is same as that of displacement.
