If maximum electron density of the ionosphere is Nmax per m3 then the critical frequency fc is given by fc=9(Nmax)1/2. Þ 1×106=9(N)1/2 Þ N = 1.2 ´ 1012 m?3

Question 1
Assertion : The electrical conductivity of earth?s atmosphere decrease with altitude. Reason : The high energy particles (i.e. g-rays and cosmic rays) coming from outer space and entering our earth?s atmosphere causes ionisation of the atoms of the gases present there and the pressure of gases decreases with increase in altitude.
