Question

A proton is going along the positive x-axis in uniform magnetic field along positive y-axis what is the direction of force experienced by the proton

Answer 1

Answer:

positive z-direction

Explanation:

1) We know that ,

Force acting on a charged particle in a magnetic field is given by :

By Lorentz Force Law,

$\vec{F}=q(\vec{v} \times \vec{B})$

In Proton here,

q > 0.

$\hat{v}=\hat{i}\\ \\ \hat{B}=\hat{j}$

Hence, Unit vector along direction of F is given by :

$\vec{F}=(\hat{i} \times \hat{j}) =\hat{k}$

Hence, Direction of Force experienced by the proton is along positive z-direction .
