AP EAMCET · PHYSICS · Magnetic Effects of Current
Two electrons, and of mass and charge are injected into the perpendicular direction of the magnetic field such that the kinetic energy of is double than that of . The relation of their frequencies of rotation, and is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
As elocity of particles are perpendicular to the magnetic field, thus the particles moves in a circle. The centripetal force is experienced by electron is qvB. So, mv2r=qvB ⇒mvr=qB⇒mω=qB⇒ω=qBm Frequency is given by f=qB2πm. As frequency is…
