A company has two factories located at $P$ and $Q$ and has three depots situated at $A, B$ and $C$. The weekly requirement of the depots at $A, B$ and $C$ is respectively $5, 5$ and $4$ units, while the production capacity of the factories at $P$ and $Q$ are respectively $8$ and $6$ units. The cost of transportation per unit is given below:

A coil of wire of certain radius has 600 turns and a self inductance of 108 mH. The self inductance of a second similar coil of 500 turns will be
A coil of mean area $500\, cm^{2}$ and having $1000$ turns is held perpendicular to a uniform field of $0.4$ gauss The coil is turned through $180^{\circ}$ in $\frac{1}{10}$ second. The average induced emf is
A coil of wire having finite inductance and resistance has a conducting ring placed coaxially within it. The coil is connected a battery at time t = 0 , so that a time dependent current $I_1(t)$ starts flowing through the coil. If $I_2(t)$ is the current induced in the ring and B (t) is the magnetic field at the axis of the coil dut to $I_1(t)$ then as a function of time (t > 0), the product $I_2(t) \,B(t)$
