What is the speed of a beam of electrons when the simultaneous influence of an electric field of 1.56×104v/m and a magnetic field of 4.62×10−3t

Explanation:

Assuming the electron is moving in a straight line, it means that the electric force and the magnetic force acting on the electron are balanced:

where

q is the electron charge

E is the electric field

v is the electron speed

B is the magnetic field

Re-arranging the equation and solving for v, we find the electron's speed:

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
