Electrostatic potential and capacitance

What is the electrostatic potential at the surface of a silver nucleus of diameter 12.4 fermi ? Atomic number silver is 47.

The electrostatic potential V at any point (x, y, z) in space is given by V=4x^(2)

The electrostatic potential on the surface of a charged concducting sphere is 100 V . Two statements are made in this regard S_(1) : at any inside the sphere, electric intensity is zero. S_(2) : at any point inside the sphere, the electrostatic potential is 100 V .

The electrostatic potential on the surface of a charged concducting sphere is 100 V . Two statements are made in this regard S_(1) : at any inside the sphere, electric intensity is zero. S_(2) : at any point inside the sphere, the electrostatic potential is 100 V .

find kinetic energy, electrostatic potential energy and total . energy of single electron in 2nd excited state of Li^(+2) atom.

What is the ratio of the electrostatic potential at the corner and the centre point of a charged conducting cube? (The potential is considered 0 at infinity)

Assertion : When two positive point charges move away from each other, then their electrostatic potential energy decreases. Reason : Change in potential energy between two points is equal to the work done by electrostatic forces.

Variation of electrostatic potential along the x - direction is shown in (Fig. 3.142). The correct statement about electric field is .

Justify that electrostatic potential is constant throughout the volume of charged conductor and has same value on its surface as inside it.

Assertion : Five charges +q each are placed at five vertices of a regular pentagon. A sixth xharge -Q is placed at the centre of pentagon. Then, net electrostatic force on -Q is zero. Reason : Net electrostatic potential at the centre is zero.
