AP EAMCET · PHYSICS · Magnetic Effects of Current
An electrically charged particle enters into a uniform magnetic induction field in a direction perpendicular to the field with a velocity \(v\). Then, it travels
- A in a straight line without acceleration
- B with force in the direction of the field
- C in a circular path with a radius directly proportional to \(v^2\)
- D in a circular path with a radius directly proportional to its velocity
Answer & Solution
Correct Answer
(D) in a circular path with a radius directly proportional to its velocity
Step-by-step Solution
Detailed explanation
By motion of charged particles in uniform magnetic field \[ r=\frac{m v}{q B} \] So, \(r \propto v\) It travels in a circular path with a radius directly proportional to its velocity.
