If \( E \) is the electric field intensity between the plates of a charged parallel plate capacitor, energy stored per unit volume in it is (permittivity of free space = \( \epsilon_0 \))
When two charges are kept in air medium, at certain distance d apart, the force between them is F. When they arc kept in a dielectric medium at the same distance of separation, the force between them becomes F/2. Thef, the dielectric constant of the medium is
The electric field strength in $N \,C\,^{-1}$ that is required to just prevent a water drop carrying a charge $1.6 \times 10^{-19} \, C$ from falling under gravity is $(g\, = \,9.8\, ms^{-2}$, mass of water drop = $0.0016\,g$)
The electric potential V at any point $(x, y, z)$ in space is given by $V = 3x^{2}$ where $x, y, z$ are all in metre. The electric field at the point (1 m, 0, 2 m) is
Four point charges (with equal magnitude of charge of $5\, C$; but with different signs) are placed at four corners of a square of side $10\, m.$ Assuming that the square is centered at the origin and the configuration of the charges are as given in the figure, the potential and the magnitude of electric field at the origin, respectively are [ Note : $k = \frac{1}{4 \pi \varepsilon_0}$]
An electron, placed in an electric field, experiences a force F of $1\, N.$ What are the magnitude and direction of the electric field E at the point where the electron is located $(e = 1.6 \times 10^{-19} C)$ ?
