A proton and an \(\alpha\)-particle start from rest in a uniform electric field. The ratio of times taken by them to travel the same distance in the field is
- A \(\sqrt{5}: \sqrt{2}\)
- B \(\sqrt{3}: 1\)
- C 2 : 1
- D \(1: \sqrt{2}\)
Answer & Solution
Correct Answer
(D) \(1: \sqrt{2}\)
Step-by-step Solution
Detailed explanation
Acceleration of \(\alpha\)-particle, \(a_r=\frac{q E}{m}=\frac{2 e E}{4}\) Acceleration of photon, \[ a_p=\frac{e E}{1} \] They travel same distances in time \(t_1\) and \(t_2\).…
