a conductor while moving through a magnetic field acting perpendicular to its length delivered it's power 200joule per second when velocity is 2m/s if velocity increase to 3m/s what will be the additional power delivered
Anyone there..!?

Answer:
The concept of work involves force and displacement; the work-energy theorem relates the net work done on a body to the difference in its kinetic energy, calculated between two points on its trajectory. None of these quantities or relations involves time explicitly, yet we know that the time available to accomplish a particular amount of work is frequently just as importan to us as the amount itself. In the chapter-openingfigure, several sprinters may have achieved the same velocity at the finish, and therefore did the same amount of work, but the winner of the race did it in the least amount of time.
Answer:
Force on rod moving in a magnetic fileld is given by:
F=BIL
Where I is the current in the rod.
According to the question;
I=0
Therefore,
F=0
Thus,
No force is exerted on the conductor in the magnetic field.
Thus, no external field is required to move the conductor at constant speed.
