AIEEE 2010 | Electromagnetic Induction Question 107 | Physics

A rectangular loop has a sliding connector $$PQ$$ of length $$l$$ and resistance $$R$$ $$\Omega $$ and it is moving with a speed $$v$$ as shown. The set-up is placed in a uniform magnetic field going into the plane of the paper. The three currents $${I_1},{I_2}$$ and $$I$$ are AIEEE 2010 Physics - Electromagnetic Induction Question 103 English

AIEEE 2010 Physics - Electromagnetic Induction Question 103 English

$${I_1} = - {I_2} = {{Blv} \over {6R}},\,\,I = {{2Blv} \over {6R}}$$

$${I_1} = {I_2} = {{Blv} \over {3R}},\,\,I = {{2Blv} \over {3R}}$$

$${I_1} = {I_2} = I = {{Blv} \over R}$$

$${I_1} = {I_2} = {{Blv} \over {6R}},I = {{Blv} \over {3R}}$$

Two coaxial solenoids are made by winding thin insulated wire over a pipe of cross-sectional area $$A=$$ $$10\,\,c{m^2}$$ and length $$=20$$ $$cm$$ . If one of the solenoid has $$300$$ turns and the other $$400$$ turns, their mutual inductance is
$$\left( {{\mu _0} = 4\pi \times {{10}^{ - 7}}\,Tm\,{A^{ - 1}}} \right)$$

$$2.4\pi \times {10^{ - 5}}H$$

$$4.8\pi \times {10^{ - 4}}H$$

$$4.8\pi \times {10^{ - 5}}H$$

$$2.4\pi \times {10^{ - 4}}H$$
