MHT CET · Physics · Magnetic Effects of Current
An electron is projected along the axis of circular conductor carrying current 1 . Electron will experience
- A a force at an angle of \(30^{\circ}\) with the axis.
- B no force.
- C a force along the axis.
- D a force perpendicular to the axis.
Answer & Solution
Correct Answer
(B) no force.
Step-by-step Solution
Detailed explanation
The velocity of the electron is parallel or antiparallel to the magnetic field.
\(F=e v B \sin \theta\)
\(\theta=0^{\circ}\) or \(180^{\circ}\)
\(\therefore \mathrm{F}=0\)
\(F=e v B \sin \theta\)
\(\theta=0^{\circ}\) or \(180^{\circ}\)
\(\therefore \mathrm{F}=0\)
