A ball A (mass

\mathrm{m}_1

) moving with velocity v experiences an elastic collision with another stationary ball B ( mass

\mathrm{m}_2

). Each ball flies apart symmetrically relative to the initial direction of motion of ball A , at an angle

\theta

. Ratio of the masses of balls

\frac{\mathrm{m}_1}{\mathrm{~m}_2}

is

Options

A $1+2 \cos \theta$
B $2 \cos 2 \theta$
C $1+2 \cos 2 \theta$
D $1+\cos 2 \theta$

Correct answer
