Physics Electrostatics Test Paper 1 for IIT-JEE, AIEEE and AIPMT


Dielectric constant of pure water is 81. Its permittivity will be:


Two similar small sphere having +q and –q charge are kept at a certain distance. F force acts between the two. If in the middle of two sphere, another similar small sphere having +q charge is kept, then it will experience a force in magnitude and direction as:



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


ABC is an equilateral triangle. Charges +q are placed at each corner. The electric intensity at O will be:



The figure show some of the electric field lines corresponding to an electric field. The figure suggest:



If a charged spherical conductor of radius 10 cm has potential V at point distant 5 cm from its center, then the potential at a point distant 15 cm from the center will be:

Electrostatics is the most basic chapters in class XII syllabus. It becomes more interesting once we start comparing it with the chapter magnetism.So many similarities are there with on basic dissimilarity, that is electric field is conservative whereas magnetic field is not. This fact has interesting consequence which is explained in a lecture by Prof. LewSee more
