A body moving towards right explodes into two pieces 1 and 2 as indicated. Then match directions of motion of the pieces is shown in column I and possible mass ratio are shown in column II.

	Column I		Column II
A		P	$m_1>m_2$
B		Q	$m_1=m_2$
C		R	$m_1<m_2$
D		S	Impossible for any  masses

Momentum remains conserved during explosion 

(a)  According to shown pieces net momentum of the pieces along x-axis is-ve  (impossible ) 

(b) Net momentum of the pieces along y-axis is non-zero (impossible)  

(c)  Along x-axis momentum remains positive   $m_1{v}_1-m_2{v}_2>0$
 $\frac{m_1}{m_2}>\frac{v_2}{v_1}>1\Rightarrow m_1>m_2$

(d)Momentum conservation along x and axes is possible for any mass ratio
