Questions
A particle is projected in a gravity free space. If the particle suffers deviation but its kinetic energy remains unchanged, then in that region
detailed solution
Correct option is B
Due to the action of electric force, the kinetic energy of the particle must change but since direction of magnetic force FB→=QV→×B→ is always perpendicular to the direction of motion and hence wok done by magnetic force on the particle is zero and its kinetic energy remains unchanged.Hence option -(2) is correctTalk to our academic expert!
