Aproton moves into the page through a magnetic field of 2 t oriented to the right in the plane of the page and through an electric field of 500 v/m oriented vertically in the plane of the page. for what velocity will the proton travel straight without veering as it moves through both fields?

Velocity of the proton,

Given:

Magnetic field, B = 2 T

Electric field, E = 500 V/m

Explanation:

For the proton to travel in a straight line without any change in direction in both the electric and magnetic field, the forces on the proton in  both the electric and magnetic fields must be equal and is given by:

where

Now,

where

E = electric field

(Since, )

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
