In a setup where a conducting wire XY of mass m and negligible resistance slides smoothly on two parallel conducting wires as shown in Fig, a closed circuit with a resistance R due to AC is formed. AB and CD are perfect conductors. The magnetic field is Bk and is independent of time. If the initial velocity is v(0) = u0, determine the velocity v(t) of the wire XY as a function of time. Which of the following options represents the correct expression for v(t)?

Options
- Au0exp (–l2B2t/mR)
- Bu0exp (–2l2B2t/mR)
- Cu0exp (–lBt/mR)
- Du0exp (–lB2t/mR)
Correct answer
A. u0exp (–l2B2t/mR)
Step-by-step solution
Correct Option is : (A)
u0exp (–l2B2t/mR)
u0exp (–l2B2t/mR)
