The ratio of kinetic energy to the total energy of an electron in a Bohr orbit of the hydrogen atom, is
An electron of mass m with an initial velocity (v0 > 0) enters an electric field (E0 = constant > 0) at t = 0. If 0 is its de-Broglie wavelength initially, then its de- Broglie wavelength at time t is
Which of the following options represent the variation of photoelectric current with property of light shown on the x-axis?
A photon and an electron (mass ) have the same energy . The ratio ( ) of their de Broglie wavelengths is: ( is the speed of light)
De-Broglie wavelength of an electron orbiting in the state of hydrogen atom is close to (Given Bohr radius )
A particle of mass is moving around the origin with a constant force pulling it towards the origin. If Bohr model is used to describe its motion, the radius of the orbit and the particle's speed in the orbit depend on as
