Question 170 of 276

This question has Statement 1 and Statement 2. 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.

Show answer and solution

Answer: (D) Statement 1 is true, Statement 2 is true, Statement 2 is the correct explanation of Statement 1.

When a charged particle enters the magnetic field in perpendicular direction then it experience a force in perpendicular direction.
i.e.
F=Bqvsin⁡θF=B q v \sin \theta
Due to which it moves in a circular path.
