The electric flux for Gaussian surface A that enclose the charged particles in free space is (given q₁ = -14 nC, q₂ = 78.85 nC, q3 = -56 nC)

In the given circuit, a charge of +80 µC is given to the upper plate of the 4 µF capacitor. Then in the steady state, the charge on the upper plate of the 3 µF capacitor is

A proton is about 1840 times heavier than an electron. When it is accelerated by a potential difference of 1 kV, its kinetic energy will be

Eight dipoles of charges of magnitude e are placed inside a cube. The total electric flux coming out of the cube will be

The inward and outward electric flux for a closed surface in units of N-m²/C are respectively 8 × 10^3 and 4 × 10^3. Then the total charge inside the surface is

An electric dipole of moment p placed in a uniform electric field E has minimum potential energy, when the angle between p and E is

An electric dipole when placed in a uniform electric field E will have minimum potential energy, if the positive direction of dipole moment makes the following angle with E

The electric potential at a point on the equatorial plane of an electric dipole depends on the distance r as

Electric charges of +10µC, +5µC, -3µC and 8µC are placed at the corners of a square of side √2m. The potential at the centre of the square is
