Maxwell's equation describes the fundamental laws of:
1. | Electricity only |
2. | Magnetism only |
3. | Mechanics only |
4. | Both (1) and (2) |
The figure shows a parallel plate capacitor being charged by a battery. If \(X\) and \(Y\) are two closed curves then during charging, \(\oint \vec{B}.d\vec{l}\) 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. | \(\oint_S \vec{H} \cdot \overrightarrow{d S}=\int_C\left(\vec{J}+\frac{d}{d t}\left(\varepsilon_0 \vec{E}\right)\right) \cdot \overrightarrow{d S}\) |
