Scattering theory — CSIR Net PYQ (Question 1)

A Scattering theory previous-year question (PYQ) from Quantum Mechanics (CSIR Net). Read the question, check the correct answer, then practise the full topic.

Question 1 of 14 · 3.5 marks

In the scattering of some elementary particles, the scattering cross-section

σ

is found to depend on the total energy

E

and the fundamental constants

h

(Planck's constant) and

c

(the speed of light in vacuum). Using dimensional analysis, the dependence of

σ

on these quantities is given by

1 $\frac{h c}{E}$
2 $\frac{h c}{E ^{3/2}}$
3 $(\frac{h c}{E})^{2}$
4 $\frac{h c}{E}$

Correct answer: Option 3
