Assertion: The geostationary satellites ...

Assertion: The geostationary satellites are launched, so as to revolve from west to east in an orbit concentric and coplanar with the equitorial plane and with a period of 24 h. Reason: These are pre-requisites for a satellite to appear stationary.

As you have learnt in the text, a geostationary satellite orbits the earth at a height of nearly 36,000 km from the surface of the earth. What is the potential due to earth’s gravity at the site of this satellite ? (Take the potential energy at infinity to be zero). Mass of the earth = 6.0Xx10^24 kg , radius = 6400 km.

A satellite is to be placed in equatorial geostationary orbit around earth for communication. Find out the minimum number of satellites that are needed to cover entire earth so that aat least one satellite is visible from any point on the equator. [ M = 6 xx 10^24 kg, R = 6400 km, T = 24 h, G = 6.67 xx 10^-11 SI units]

An artificial satellite is revolving around a planet fo mass M and radius R, in a circular orbit of radius r. From Kepler's third law about te period fo a satellite around a common central bdy, square of the period of revolution T is proportional to the cube of the radius of the orbit r. Show usingn dimensional analysis, that T = k/R sqrt((r^3)/(g)) , where k is a dimensionless constant and g is acceleration due to gravity.

Bohr's model of hydrogen atom In order to explain the stability of atom and its line spectra, Bohr gave a set of postulates: An electron in an atom revolves in certain circular orbit around the nucleus. These are the orbits for which mvr=(nh)/(2pi) In these allowed orbits, the electron does not radiate energy. When an electron jumps from higher energy level E_(n_2) to lower energy orbit E_(n_1) , radiation is emittd and frequency of emitted electron is given by v=(E_(n_2)-E_(n_1))/h . Further the radius of the n^(th) orbit of hydrogen atom is r=(n^2h^24piepsilon_0)/(4pi^2me^2) and energy of the n^(th) orbit is given by E_n=-13.6/n^2 eV . What would happen, if the electron in an atom is stationary?

A satellite is to be placed in equatorial geostationary orbit around earth for communication. calculate height of such a satellite. [ M = 6 xx 10^24 kg, R = 6400 km, T = 24 h, G = 6.67 xx 10^-11 SI units]
