The kinetic energy acquired by a mass m in travelling a certain distance d, starting from rest, under the action of a force F such that the force F is directly proportional to t is
A planet moves around sun in nearly circular orbit period of revolution 't', radius of orbit r mass of sun m.
Time period if direcyly proportional to mass of sun, distance between planet and sun and universal gravitational constant.
Prove T2 is directly proportional to r3
The time taken by the electron in one complete revolution in the nth Bohr's orbit of the hydrogen atom is:
