Question

Find the ratio of velocities of two bodies if the momenta of both are the same and the masses are in the ratio of 1 : 2. ​

• A. 1 : 2
• B. 2 : 1
• C. 1 : 4
• D. 4 : 1

Answer 1

The correct option is B 2 : 1

P = $mv$
$m1v1$ = $m2v2$
$\frac{v1}{v2}$ = $\frac{m2}{m1}$ = ${\frac{1}{2}}^{-1}$ = $2:1$
[Momentum (P) is same]​
