Question

A particle is moving in a circular path of radius r. If v



is its velocity vector, r



is its position vector (taking

centre of circle as origin) and a



is acceleration of particle, then match the entries of two columns.

Column-I Column-II

(A) If the particle is moving with constant speed (P) v a. 0

 

(B) If the particle is moving with increasing speed (Q) v a. 0

 

(C) If the particle is moving with decreasing speed (R) v r . 0

 

(D) If particle is moving with increasing tangential (S) v a. 0

 

acceleration (parallel to its velocity)

(T) r a. 0​
