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 fi

Options

  1. AStatement 1 is false, Statement 2 is true.
  2. BStatement 1 is true, Statement 2 is true, Statement 2 is not the correct explanation of Statement 1.
  3. CStatement 1 is true, Statement 2 is false.
  4. DStatement 1 is true, Statement 2 is true, Statement 2 is the correct explanation of Statement 1.

Correct answer

D. Statement 1 is true, Statement 2 is true, Statement 2 is the correct explanation of Statement 1.

Step-by-step solution

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