A $800$ turn coil of effective area $0.05{\text{m}}^2$ is kept perpendicular to a magnetic field $5\times 10^{-5}\text{T}$. When the plane of the coil is rotated by $90^{\circ }$ around any of its coplanar axis in $0.1\text{s}$, the emf induced in the coil will be:

The radius of circle, the period of revolution, initial position and sense of revolution are indicated in the fig. $y$ -projection of the radius vector of rotating particle $P$ is:

A parallel plate capacitor of capacitance $20\mu \text{F}$ is being charged by a voltage source whose potential is changing at the rate of $3\text{V/s}$. The conduction current through the connecting wires, and the displacement current through the plates of the capacitor, would be, respectively:

In an experiment, the percentage of error occurred in the measurement of physical quantities $A,B,C$ and $D$ are $1\%,2\%,3\%$ and $4\%$ respectively. Then the maximum percentage of error in the measurement $X$, where $X=\frac{A^2{B}^{1/2}}{C^{1/3}{D}^3}$, will be:

A cylindrical conductor of radius $R$ is carrying a constant current. The plot of the magnitude of the magnetic field $B$ with the distance $d$ from the centre of the conductor, is correctly represented by the figure:
