Two parallel large thin metal sheets have equal surface charge densities (σ = 26.4 × 10^-12 Cm^-2 ) of opposite signs. The electric field between these sheets is

Potential and field strength at a certain distance from a point charge are 600 V and 200 NC ^-1 . Distance of the point from the charge is

Torque acting on an electric dipole in a uniform electric field is maximum, if the angle between p and E is

An electric dipole of the dipole moment p is placed in a uniform electric field E. The maximum torque experienced by the dipole is

Dipole is placed parallel to the electric field. If Q is the work done in rotating the dipole by 60°, then work done in rotating 180° is

The ratio of electric field and potential (E / V ) at mid-point of electric dipole, for which separation l is

What is the nature of Gaussian surface involved in Gauss law of electrostatic?

The electric charges are distributed in a small volume. The flux of the electric field through a spherical surface of radius 10 cm surrounding the total charge is 20 Vm. The flux over a concentric sphere of radius 20 cm will be
