A circular wire loop of radius R is placed in the x-y plane centered at the origin O. A square loop of side a(altltR) having two turns is placed with its centre at = root 3 R along the axis of hte circular wire loop, as shown in figure. The plane of the square loop makes an angle of 45∘ with respect to the z-axis. If the mutual inductance between the loops is given bu μ0a^2/ 2p/2 R, then the value of p is

A long circular tube of length 10 m and radius 0.3 m carries a current I along its curved surface as shown . A wire – loop of resistance 0.005 ohm and of radius 0.1 m is placed inside the tube its axis coinciding with the axis of the tube . The current varies as I = I0 cos ( 300 t ) where I0 is constant. If the magnetic moment of the loop is Nμ 0I0 sin( 300 t ), then ‘N’ is
