A \( 1 \, \text{m} \) long metal rod \( AB \) completes the circuit as shown in figure. The area of circuit is perpendicular to the magnetic field of \( 0.10 \, \text{T} \). If the resistance of the total circuit is \( 2 \, \Omega \) then the force needed to move the rod towards right with constant speed \( (v) \) of \( 1.5 \, \text{m/s} \) is ______________ \( \text{N} \).
