An electron is moving towards x-axis. An electric field is along y-direction then path of electron is

At a point 20 cm from the centre of a uniformly charged dielectric sphere of radius 20 cm, the electric field is 100 V/m. The electric field at 3 cm from the centre of the sphere will be

The dimension of (1/2)ɛ₀E²(ɛ₀ : permittivity of free space; E: electric field) is

In the rectangle, shown below, the two corners have charges q₁ = –5 µC and q₂ = +2.0 µC. The work done in moving a charge + 3.0 µC from B to A is (take 1/4 πɛ₀ =10¹⁰ N-m² / C²)

A cube of a metal is given a positive charge Q. For the above system, which of the following statements is true?

A spherical conductor of radius 2 m is charged to a potential of 120 V. It is now placed inside another hollow spherical conductor of radius 6 m. Calculate the potential to which the bigger sphere would be raised.

A charge (–q) and another charge (+Q) are kept at two points A and B respectively. Keeping the charge (+Q) fixed at B, the charge (–q) at A is moved to another point C such that ABC forms an equilateral triangle of side l. The net work done in moving the charge (–q) is

A particle of mass \'m\' and charge \'q\' is accelerated through a potential difference of V volt. its energy will be

4 point charges each +q is placed on the circumference of a circle of diameter 2d in such a way that they form a square. The potential at the centre is

Consider two point charges of equal magnitude and opposite sign separated by a certain distance. The neutral point between them
