Attraction & repulsion of atom:
It can be observed, that if two negatively charged bodies are brought together, there is a force of repulsion between them. Similarly if two positively charged bodies are brought together there is a force of repulsion. However, if a positively charged body is brought close to a negatively charged body, they attract each other. Hence:
Like Charges Repel, Unlike Charges Attract.
The force of attraction or repulsion is governed by an inverse square lawUNIT OF CHARGE
The charge on an electron is very small, therefore a more practical unit of charge called a Coulomb, has been chosen:
One Coulomb = 6.29 x 1018 electrons
A longitudinal wave with a frequency of 34 Hz takes 1.0 s to travel the length of a 2.5 m Slinky (see the figure). Determine the wavelength of the wave. λ = ( )m
a) Can a gravitational field be added vertorially to an electric field to get a total field? Describe it. b) Can two equipotential surfaces cut down each other? describe it.
Q. State Brewster's law. Brewster's law the digression of the polarising angle is numerically equal to the refractive index of the medium. That is tan ip = μ

How to calibrate an oscilloscope?
How are vibrational modes of carbon dioxide molecule represented? Generally the modes are represented through three integers (mnq): a. (moo) represents Symmetric stretching
In computing the electric field at a point call it point P in the first quadrant of a Cartesian coordinate system because of a continuous charge distribution from 0 to L on the x-a
There is a maximum depth at which a diver can breathe through snorkel tube because as the depth increases, so does the pressure difference, tending to collapse the diver's lungs. S
