JEE Main 2012 Physics question
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.
Answer: (4)
Solution
The magnetic force is perpendicular to the field and to the velocity (Statement 2 true), so it does no
