Maxwell's equation describes the fundamental laws of:
1. | Electricity only |
2. | Magnetism only |
3. | Mechanics only |
4. | Both (1) and (2) |
1. | Faraday's law of induction |
2. | Modified Ampere's law |
3. | Gauss's law of electricity |
4. | Gauss's law of magnetism |
The figure shows a parallel plate capacitor being charged by a battery. If \(X\) and \(Y\) are two closed curves then during charging, \(\oint \vec{B} . \vec{dl}\) is zero along the curve:
1. | \(X\) only |
2. | \(Y\) only |
3. | Both \(X\) & \(Y\) |
4. | Neither \(X\) nor \(Y\) |
1. | \(\oint_S \vec{E} \cdot \overrightarrow{d S}=\frac{1}{\varepsilon_0} \int_V \rho d V\) |
2. | \(\oint_S \vec{B} \cdot \overrightarrow{d S}=\frac{m}{\mu_0}\) |
3. | \(\oint_S \vec{E} \cdot \overrightarrow{d l}=-\frac{d}{d t} \int_S \vec{B} \cdot \overrightarrow{d S}\) |
4. | \(\oint_S \vec{H} \cdot \overrightarrow{d S}=\int_C\left(\vec{J}+\frac{d}{d t}\left(\varepsilon_0 \vec{E}\right)\right) \cdot \overrightarrow{d S}\) |
