Two particles having masses 4g4g and 16g16g respectively are moving with equal kinetic energies. The ratio of the magnitudes of their linear momentum is n:2n:2. The value of nn will be ___.

Show answer and solution

Answer: 1

p122×4=p222×16\dfrac{{p}_{1}^{2}}{2\times 4}=\dfrac{{p}_{2}^{2}}{2\times 16}
p1p2=12\dfrac{{p}_{1}}{{p}_{2}}=\dfrac{1}{2}
