Two parallel plates having a p.d. of 250V between them are spaced 1mm apart.
Determine the electric field strength.
Find also the electric flux density when the dielectric among the plates is
(a) air and
(b) mica of relative permittivity 5
Give a mathematical expression for linear width of principal maxima in case of single slit Fraunhofer diffraction.
Capacitance: If we increase the voltage between the plates, the charge increases, but the ratio of charge to voltage remains the same. This ratio gives the capacitance (C) of
Relativity principle: The principle, employed through Einstein's relativity theories, that the laws of physics are the similar, at least qualitatively, in all of frames. That

The electrostatic shielding may be found by protecting and enclosing the sensitive instruments inside a hollow conductor due to inside hollow conductors, electric fields is zero.
The nucleus of helium contains : (1)Four protons (2)Four neutrons (3)Two neutrons and two protons (4)Four protons and two electrons Ans: (3)Two neutrons and two prot
Defects of vision and their correction There is a simple relationship between the focal length F ,the object distance P and the image distance Q of a thin lens fig(1).
why wouldn''t you be electrocuted if you walked under an electric transmission line during a rainstorm?
Q. How does the laser printer works? Answer:- When a text or else image is entered into the CPU it produces a series of varying voltages. This manages a LED (light emittin
Moderation: In a nuclear reactor, the fast moving neutron has to be slowed down by the use of Boron rods before they are able to cause further fission. The process of slowing d
