A ponit P is moving in uniform circular motion with radius 3m. Let at some instant the acceleration of the point is a^{\to}=(6i^{\^}-4j^{\^})m{/}s^2, the position vector is r^{-} and velocity is r^{\to} and velocity vector is v^{\to}. The correct statement is

Correct Answer is : →v.→a=0 and →r×→a=0

v^{\to}.a^{\to}=0 and r^{\to}\timesa^{\to}\neq0

v^{\to}.a^{\to}\neq0 and r^{\to}\timesa^{\to}\neq0

v^{\to}.a^{\to}=0 and r^{\to}\timesa^{\to}=0

v^{\to}.a^{\to}\neq0 and r^{\to}\timesa^{\to}=0
