Give equation of momentum of photon. Is it applicable for proton and electron.

Bernoulli 's equation is applicable to points

If a proton is projected in a direction perpendicular to a uniform magnetic field with velocity v and and electron is projected along the line of force, what will happen to proton and electron?

The momentum of a photon of wavelength lambda is

Linear momentum of electron in nth orbit is

The mass of a H- atom is less than the sum of the masses of a proton and electron. why is this?

Give any two applications of photoelectric cell

What is the momentum of a photon of frequency nu ?

Assertion: An electron and proton enters a magnetic field with equal velocities, then, the force experienced by the proton will be more than electron. The mass of proton is 1837 times more than electron.

The de Broglie wavelength of an electron moving with a velocity of 1.5×10 8 m/s is equal to that of a photon. Find the ratio of the kinetic energy of the photon to that of the electron.

If the position of the electron is measured within an accuracy of ± 0.002 nm, calculate the uncertainty in the momentum of the electron. Suppose the momentum of the electron is h//4pi m xx 0.05 nm , is there any problem in defining this value.
