MHT CET · Physics · Magnetic Effects of Current
An electron is projected along the axis of circular conductor carrying current ' \(I\) ' The electron will experience
- A a force perpendicular to axis
- B a force along the axis
- C a force at angle \(30^{\circ}\) with the axis
- D no force
Answer & Solution
Correct Answer
(D) no force
Step-by-step Solution
Detailed explanation
The direction of the magnetic field will be along the axis. The angle between the velocity and the magnetic field will be \(0^{\circ}\) or \(180^{\circ}\). The force is given by \(\mathrm{F}=\mathrm{qvB} \sin \theta\)
If \(\theta=0^{\circ}\) or \(180^{\circ}, \mathrm{F}=0\)
If \(\theta=0^{\circ}\) or \(180^{\circ}, \mathrm{F}=0\)
