Two particles with masses in the ratio 1:4 are moving with equal kinetic energies. The magnitude of their linear momentums will confirm to the ratio
- A. 1:8
- B. 1:$\sqrt{2}$
- C. $\sqrt{2}$:1
- D. 1:2
Answer: D. 1:2
Explanation: $p = \sqrt{2mK}$. Ratio $p_1/p_2 = \sqrt{m_1/m_2} = \sqrt{1/4} = 1/2$.
