154769 A coil of wire of a certain radius has 100 turns and a self inductance of $15 \mathrm{mH}$. The self inductance of a second similar coil of 500 turns will be

154770 A coil of 100 turns carries a current of $5 \mathrm{~mA}$ and creates a magnetic flux of $10^{-5}$ Weber. The inductance is

154771 Figure shows the cross-sectional view of the hollow cylindrical conductor with inner radius $R$ and outer radius $2 R$, carrying uniformly distributed current $i$ along its axis. The magnetic induction at point $P$ at a distance $3 R / 2$ from the axis of the cylinder will be
