Imagine a neutral particle of same mass m as electron revolving around a proton of mass `M_(p)` only under newton's gravitational force. Assuming Bohr's quantum condition, the radius of electron orbit is given by:

A particle of mass m is located inside a spherical shell of mass M and radius R. The gravitational force of attraction between them is

Two particles of same mass m go around a circle of radius R under the action of their mutual gravitational attraction. The speed of each particle is ,

An electron (mass m) and a proton (mass M) are accelerated with same potential difference, then

Two satellites of mass M_A and M_B are revolving around a planet of mass M in radius R_A and R_B respectively. Then?

In a hypothetical concept, electron of mass m_(e) revolves around nucleus due to gravitational force of attraction between electron and proton of mass m_(p) . If the radius of circular path of electron is r, then the speed of electron is

The key feature of Bohr's spectrum of hydrogen atom is the quantization of angular momentum when an electron is revolving around a proton. We will extend this to a general rotational motion to find quantized rotational energy of a diatomic molecule assuming it to be rigid.The rule to be applied is Bohr's quantization condition. In a CO molecule, the distance between C (mass = 12 a. m. u ) and O (mass = 16 a.m.u) where 1 a.m.u = (5)/(3) xx 10^(-27) kg , is close to

Four similar particles of mass m are orbiting in a circle of radius r in the same direction and same speed because of their mutual gravitational attractive force as shown in the figure . Speed of a particle is given by
