Explanation:
The diagram for this question is shown on the first uploaded image
From the question we are told that
the length of the conducting rod is
The resistance is
The magnetic field is
The speed of the rod is
The emf induced is
substituting values we have
From ohm law the induced current would be
substituting values we have
The direction anticlockwise this because according to lenze law the current due to change in magnetic field will act in the opposite direction of the force causing the magnetic field to change
