Angular momentum of an electron in hydrogen atom is (3h)/(2 pi) ( h is the Planck's constant). The K. E of the electron is

A quantity X is given by (me^(4))/(8epsilon_(0)^(2)ch^(3)) where m is mass of electron, e is the charge of electron, epsilon_(0) is the permittivity of free space, c is the velocity of light and h is the Planck's constant. The dimensional formula for X is the same as that of :

In a metre bridge experiment null point is obtained at 20 cm from one end of the wire when resistance X is balanced against another resistance Y. If X < Y , then where will be the new position of the null point from the same end, if one decides to balance a resistance of 4 X against Y ?

We can say that the energy of a photon of frequency v is given by E = hv, where h is planck's constant. The momentum of a photon is p = h//lambda, where lambda is the wavelenght of photon, then we may conclude that velocity of light is equal to
