PhysicsEasysingle choice

Two bodies $A$ and $B$ having masses in the ratio of $3 : 1$ possess the same kinetic energies. The ratio of linear momenta of $B$ to $A$ is

Options:

Answer:

Solution:

As $\frac{1}{2} m_{A} v_{A}^{2} = \frac{1}{2} m_{B} v_{B}^{2}$

$\frac{v_{A}}{v_{B}} = \sqrt{\frac{m_{B}}{m_{A}}};$

$\frac{P_{B}}{P_{A}} = \frac{m_{B} v_{B}}{m_{A} v_{A}}$

$= \frac{m_{B}}{m_{A}} \sqrt{\frac{m_{A}}{m_{B}}} = \sqrt{\frac{m_{B}}{m_{A}}} = \frac{1}{\sqrt{3}}$
