Particle A of mass m₁ moving with velocity

\left( {\sqrt3\widehat i + \widehat j} \right)m{s^{ - 1}}

collides with another particle B of mass m₂ which is at rest initially. Let

\overrightarrow {{V_1}}

and

\overrightarrow {{V_2}}

be the velocities of particles A and B after collision respectively. If m₁ = 2m₂ and after collision

\overrightarrow {{V_1}} =

\left( {\widehat i + \sqrt 3 \widehat j} \right)

, the angle between

\overrightarrow {{V_1}}

and

\overrightarrow {{V_2}}

is :
