A charged particle enters a uniform magnetic field at an angle of \(45 ^\circ\) with the field. The path along which the particle moves in the field will be
- A linear
- B circular
- C helical with axis along magnetic field
- D helical with axis perpendicular to magnetic field
Answer & Solution
Correct Answer
(C) helical with axis along magnetic field
Step-by-step Solution
Detailed explanation
Velocity Components: The component perpendicular to the field \((v \sin \theta)\) provides the centripetal force for circular motion, while the component parallel to the field \((v \cos \theta)\) moves the particle forward at a constant speed. Resultant Path: The combination of…
