Two particles A and B have the same charge. The mass of A is four times the mass of B. They are projected towards a silver nucleus, in different experiments, with the same momentum. The distance of closest approach will be
Options:
Answer:
B
Solution:
KE = . For the same momentum, the heavier particle A has the smaller kinetic energy.
, so a smaller KE gives a greater distance of closest approach.
dA : dB = mA : mB = 4 : 1, so d is greater for A.
Answer: (B).
