TS EAMCET · Physics · Magnetic Effects of Current
Two charged particles \(A\) and \(B\) of masses \(m\) and \(2 m\), charges \(2 q\) and \(3 q\) respectively moving with same velocity enter a uniform magnetic field such that both the particles make same angle ( \( \lt 90^{\circ}\) ) with the direction of the magnetic field. Then the ratio of the pitches of the helical paths of the particles \(A\) and \(B\) is
- A \(4: 3\)
- B \(3: 2\)
- C \(3: 4\)
- D \(2: 3\)
Answer & Solution
Correct Answer
(C) \(3: 4\)
Step-by-step Solution
Detailed explanation
The pitch of the helical path in uniform magnetic field is given by \(\begin{aligned} p & =\frac{2 \pi m}{q^B}(v \cos \theta) \\ & \Rightarrow p \alpha \frac{m}{q} \end{aligned}\)…
