I'm not quiet sure what exactly this question is asking but some examples of vectors include displacement, velocity, position, force, and torque.
A diagram with atoms of the same color and size.
Answer:
Explanation:
Given
mass of rod is M
Distance between rails is L
If the direction of magnetic field is directed upwards
If rod is moving right then,
Area enclosed is increasing therefore a Clockwise current will induce
and if rod is moving left then enclosed area is decreasing therefore an anticlockwise current will setup in the circuit
(b)Induced EMF will be

where v=velocity of rod
and current is 

(c)Force necessary to move rod with constant velocity v is
