| This question has Statement 1 and Statement 2. [JEE ONLINE 26-05-2012] |
| Of the four choices given after the Statements, choose the one that best describes the two Statements. |
| Statement 1: A charged particle is moving at right angle to a static magnetic field. During the motion the kinetic energy of the charge remains unchanged. |
| Statement 2: Static magnetic field exert force on a moving charge in the direction perpendicular to the magnetic field. |
A) Statement 1 is false, Statement 2 is time.
B) Statement 1 is time, Statement 2 is time, Statement 2 is not the correct explanation of Statement 1.
C) Statement 1 is true. Statement 2 is false.
D) Statement 1 is time, Statement 2 is time, Statement 2 is the correct explanation of Statement 1.
Correct Answer: D
Solution :
[d] When a charged particle enters the magnetic field in perpendicular direction then it experience a force in perpendicular direction. i.e. \[F=Bqv\sin \theta \] Due to which it moves in a circular path.
