Two particles having masses 4 g and 16 g respectively are moving with equal kinetic energies. The ratio of the magnitudes of their linear momentum is n : 2. The value of n will be ___________.
Answer (integer)
1
Solution
$\because$ relation b/w kinetic energy & momentum is<br><br>$P = \sqrt {2mKE}$ ($\because$ KE = same)<br><br>$\Rightarrow$ ${{{p_1}} \over {{p_2}}} = \sqrt {{{{m_1}} \over {{m_2}}}}$<br><br>$\Rightarrow$ ${n \over 2} = \sqrt {{4 \over {16}}}$<br><br>$\Rightarrow$ $n = 1$
