Question

Magnetic field is acting perpendicularly into the plane of paper as shown in the diagram. A positive
charged particle q entered in to the magnetic field with speed v at right angles to the direction of
magnetic field



a) The direction of magnetic force resulted on the charge q is in the upward direction along the plane
of the paper
b) The magnitude of magnetic force resulted is F=qvB
c) The workdone by the magnetic force on the charged particle is zero
Choose the correct option from above and give explanation​

Answer 1

Answer:

RHR-1 states that, to determine the direction of the magnetic force on a positive moving charge, you point the thumb of the right hand in the direction of v, the fingers in the direction of B, and a perpendicular to the palm points in the direction of F.
