If the electric field established by three point charges Q, 2Q and 3Q exert a force 3F on 3Q and 2F on 2Q, then what is the force exerted on the point charge Q?
An infinitely long uniform solid wire of radius a carries uniform dc current of density $$\overrightarrow {\text{J}} .$$
The magnetic field at a distance r from the center of the wire is proportional to
A parallel plate air-filled capacitor has plate area of 10-4 m2 and plate separation of 10-3 m. It is connected to a 2 V, 1.8 GHz source. The magnitude of the displacement current is $$\left( {{\varepsilon _0} = \frac{1}{{36\pi }} \times {{10}^{ - 9}}{\text{F}}{{\text{m}}^{ - 1}}} \right)$$
If the electric field vector is $$\overline E = - 2{\overline a _x} + 3{\overline a _y} + 5{\overline a _z}$$ and the magnetic field vector is $$\overline H = {\overline a _x} + 3{\overline a _y} - 4{\overline a _z},$$ then $$\overline E \times \overline H $$ is equal to
