Q In the given diagram an electron is given a speed v at P towards
A then time after which it comes out of the magnetic field B m is
the mass of electron-

1   m π 2 e B 2   2 m π e B 3   3 m π
4 e B
4 It will never come out of the magnetic field

Dear Student,
Radius of the path =mveBso path length through which comes out =π2mveBhence time =length velocity=mvπ2eBv=mπ2eB

Q. In the given diagram an electron is given a speed v at P towards A then time after which it comes out of the magnetic field B m is the mass of electron- 1 . m π 2 e B 2 . 2 m π e B 3 . 3 m π 4 e B 4. It will never come out of the magnetic field

Q. In the given diagram an electron is given a speed v at P towards A then time after which it comes out of the magnetic field B m is the mass of electron-

$1 . \frac{m π}{2 e B} 2 . \frac{2 m π}{e B} 3 . \frac{3 m π}{4 e B}$
4. It will never come out of the magnetic field
