Vedclass · Answer

(B) $1$. According to the right-hand thumb rule,the magnetic field produced by the current-carrying conductor at the position of the electron stream (below the conductor) is directed into the plane of the paper.$2$. The electrons are moving to the right. The force on a moving charge $q$ in a magnetic field $B$ is given by the Lorentz force formula $F = q(v 	imes B)$.$3$. Since the charge of an electron is negative $(q = -e)$,the direction of the force is opposite to the direction of $(v 	imes B)$.$4$. Using the right-hand rule for the cross product $(v 	imes B)$,where $v$ is to the right and $B$ is into the page,the direction of $(v 	imes B)$ is upward. $5$. Therefore,the force on the electrons is downward. Alternatively,using Fleming's left-hand rule for negative charges,the force is directed downward.

$A$ stream of electrons is projected horizontally to the right. $A$ straight conductor carrying a current is supported parallel to the electron stream and above it. If the current in the conductor is from left to right,then what will be the effect on the electron stream?
