SATHEE: Work Energy And Power Question 170

Work Energy And Power Question 170

Question: A neutron having mass of $1.67 \times 10^{- 27} k g$ and moving at $10^{8} m / s$ collides with a deutron at rest and sticks to it. If the mass of the deutron is $3.34 \times 10^{- 27} k g$ then the speed of the combination is [CBSE PMT 2000]

Options:

A) $2.56 \times 10^{3} m / s$

B) $2.98 \times 10^{5} m / s$

C) $3.33 \times 10^{7} m / s$

D) $5.01 \times 10^{9} m / s$

Show Answer

Answer:

Correct Answer: C

Solution:

According to law of conservation of momentum.

Momentum of neutron = Momentum of combination therefore $1.67 \times 10^{- 27} \times 10^{8} = (1.67 \times 10^{- 27} + 3.34 \times 10^{- 27}) v$ \ $v = 3.33 \times 10^{7} m / s$
