Vedclass · Answer

(A) When a metallic rod is placed in a uniform external electric field $E_0$ directed from left to right,the free electrons in the metal experience a force in the direction opposite to the electric field (i.e.,towards the left end $A$).As a result,negative charges accumulate at end $A$ and positive charges are left at end $B$.This charge separation creates an induced electric field $E_{in}$ inside the rod,which is directed from the positive end $B$ to the negative end $A$.Therefore,the correct option is that there will be an induced electric field from $B$ to $A$ inside the rod.

$A$ metallic rod is placed in a uniform electric field. Select the correct option.
