Question

Which description best matches the image below of a hand that is using the right-hand palm rule?




A. A proton moving toward you in a magnetic field that points up will experience a force to the right.

B. A proton moving up in a magnetic field that points to the right will experience a force toward you.

C. A proton moving to the right in a magnetic field that points up will experience a force toward you.

D. A proton moving to the right in a magnetic field that points toward you will experience a force up.

Answer 1

The correct option is C. i.e.A proton moving to the right in a magnetic field that points up will experience a force toward you.

Explanation:

As seen in the diagram, the magnetic field points in the upward direction. The charge moves towards the right. Then, as per the right hand thumb rule, the force will be towards you. 

Because we know, F = qvB
where q is charge
v is the velocity of the charge.
B is the magnetic field.

Force is perpendicular to the plane of v & B.
