Electro Magnetic Induction And Alternating Currents Question 466

Question: An L-shaped conductor rod is moving in transverse magnetic field as . Potential difference between ends of the rod is maximum if the rod is moving with velocity

Options:

A) 4i^6j^,m/s

B) ,4i^+6j^,m/s

C) 3i^+2j^,m/s

D) 13i^,m/s

Show Answer

Answer:

Correct Answer: C

Solution:

  • For maximum potential difference the velocity must be perpendicular to the line AB, and so

    v=v,sin,θi^+v,cosθj^

    =v[3i^+2j^]=v[3i^+2j^]
