Question

Which among the following statements is CORRECT? The direction of the magnetic force on a charged particle moving in a magnetic field is always perpendicular to the plane formed by the velocity and magnetic field vectors If the current through a wire placed in a magnetic field doubles, then the magnetic force on the wire quadruples. The direction of the magnetic force on a charged particle moving in a magnetic field is always in the same plane as the velocity and magnetic field vectors The magnetic force on a charged particle moving through a non-zero magnetic field can be zero provided the particle travels at 90° with respect to the magnetic held

Answer 1

The correct answer is option 1

The problem has been solved by using the basic concept of Lorentz force on a charged particle .

The details is given below

son your statements the first statement Among ng is the the airen given correct Reason: According to Lorentz Law the magnetic partiele velocity moving i in. force acting on a charged a magnetic field (5) with given by ² q uxo where a charrge. Now let us consider, there is a uniform magnetic field along yaxis. The particle is moving with uniform velocing along a axis. from above equation 4 vax - quB ax îný - QvB & is along z axis (it Perspendicular to the plane) xy magnetic formed by velocity and So the direction of the magnetic force on. charged particle moving in a magnetic field is always perpendicular to the plane formed by the relocity and magnetic field vector. altermate representation xp plane
