List of top Physics Questions on Electrostatic potential asked in AP EAMCET

Electric field intensity and electric potential at a point due to a point charge are 600 V/m and -3600 V respectively. The distance of the point from the charge and the magnitude of the charge are:
When a parallel plate capacitor is charged up to 95 V, its capacitance is \( C \). If a dielectric slab of thickness 2 mm is inserted between plates and the plate separation is increased by 1.6 mm such that the potential difference remains constant, find the dielectric constant of the material:
The electrostatic potential energy of the electron in an orbit of hydrogen is \( -6.8 \) eV. The speed of the electron in this orbit is (C is the speed of light in vacuum):
“Introduction of a small charged sphere into a larger one allows us to keep piling up a larger and larger amount of charge on the latter” – This is the principle of the:
Two separated conducting spheres \(S_1\) and \(S_2\), of radii \(3R/4\) and \(R/4\) having \(15 \mu C\) and \(-3 \mu C\) charges respectively are at a large distance. They are now connected by a conducting wire. After a long time, the charges on \(S_1\) and \(S_2\) respectively are:
A 200 volt battery is connected across the series combination of two capacitors 4 \(\mu\)F and 6 \(\mu\)F. The amount of energy stored in this series combination is:
Find linear charge density if infinite line charges produce a field of 9 x 104 and the distance is 2 cm.
Two positive point charges of \(10 \, \mu C\) and \(12 \, \mu C\) are placed \(10 \, cm\) apart in air. The work done to bring them \(6 \, cm\) closer is
