The electric field inside a spherical shell of uniform surface charge density is

Electric lines of force about negative point charge are

A uniform electric field having a magnitude E₀ and direction along the positive X-axis exists. If the potential V is zero at x = 0, then its value at X = +x will be

Three charges 2q, – q, – q are located at the vertices of an equilateral triangle. At the centre of the triangle

Figure shows the electric lines of force emerging from a charged body. If the electric field at A and B areEA and EB respectively and if the displacement between A and B is r, then

In the electric field of a point charge q, a certain charge is carried from point A to B, C, D and E. Then, the work done

An electron and a proton are in a uniform electric field, the ratio of their accelerations will be

Two parallel plates have equal and opposite charge. When the space between them is evacuated, the electric field between the plates is 2 × 10⁵ V/m. When the space is filled with dielectric, the electric field becomes 1 × 10⁵ V/m. The dielectric constant of the dielectric material

The insulation property of air breaks down at E = 3 × 10⁶ volt / metre. The maximum charge that can be given to a sphere of diameter 5 m is approximately (in coulombs)
