A proton, a deutron and an \(\alpha\)-particle having the same momentum, enters a region of uniform electric field between the parallel plates of a capacitor. The electric field is perpendicular to the initial path of the particles. Then the ratio of deflections suffered by them is
- A \(1: 2: 8\)
- B \(1: 2: 4\)
- C \(1: 1: 2\)
- D None of these
Answer & Solution
Correct Answer
(A) \(1: 2: 8\)
Step-by-step Solution
Detailed explanation
The deflection suffered by charged particle in an electric field is \(y=\frac{q E L D}{m \mu^2}=\frac{q E L D}{p^2 / m} \quad(p=m u)\) \(\Rightarrow \quad y \propto \frac{q m}{p^2}\)…
