Speed of a particle moving in a circle of radius 2 m varies with time as

v = 2t

(SI units). At

t = 1

s match the following two columns :

Column I	Column II (SI units)
(a) $\mathbf{a} \cdot \mathbf{v}$	(p) $2\sqrt{2}$
(b) $\mathbf{a} \times \mathbf{\omega}$	(q) 2
(c) $\mathbf{v} \cdot \mathbf{\omega}$	(r) 4
(d) $\mathbf{v} \times \mathbf{a}$	(s) None

Here, symbols have their usual meanings.
