A body is moving on a rough horizontal table in a circular path being tied to a nail by a string. While the body is in motion, match the quantities in column-A with their description in column-B.

Column-A		Column-B
(a)	Acceleration of body	(p)	Changes direction but constant in magnitude
(b)	Friction force on body	(q)	Changes magnitude but constant in direction
(c)	Angular momentum of the particle	(r)	Changes direction as well as magnitude
(d)	Normal force by table	(s)	Direction as well as the magnitude is constant

• A

  a$\to$p, b$\to$r, c$\to$q, d$\to$s

• B

  a$\to$r, b$\to$p, c$\to$q, d$\to$s

• C

  a$\to$r, b$\to$p, c$\to$s, d$\to$q

• D

  a$\to$p, b$\to$r, c$\to$q, d$\to$s
