Question

A force of 10n is required to move s conducting loop through a non uniform

Answer 1

Answer:

20watt

Explanation:

de/St=u=f×v. I fill that you got answer

Answer 2

As the loop is conducting which means that there would be magnetic field and electrical energy associated with it.

• As given force is F=10 N
• The velocity is v=2 m/sec
• So to get the rate of change of the electrical energy in the loop is
• F=( E +B)v
• B is the magnetic field, E is the electrical field.
• Now substitute in above
• F=(E+0)v
• Put the given values.
• Here B=0 because the non-uniform magnetic field.
• 10=(E+0)2
• E=5 W
• That is the answer.
