Solution

The correct option is B sky above our head
Atmospheric pressure is the pressure exerted by the weight of air in the atmosphere of Earth (or that of another planet). In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point.
Answer (A) sky above our head

Q. Radiation from the Sun reaching Earth (just outside the atmosphere) has an intensity of

1.4 {kW/m}^{2}

. If

F_{R}

is the force on Earth due to radiation pressure and

is the force due to the Suns gravitational attraction, then select the correct option (Assuming that Earth (and its atmosphere) behaves like a flat disk perpendicular to the Suns rays and that all the incident energy is absorbed)

[Take R_{e a r t h} = 6400 km, M_{e a r t h} = 5.98 \times 10^{24} kg, M_{s u n} = 2 \times 10^{30} kg, Distance between the centres of Sun and Earth = 1.5 \times 10^{8} km]

Q. The earth is acted upon by gravitational force of attraction due to the sun. Then why does the earth not fall towards the sun?

Compare the gravitational forces exerted by the Sun and the moon on the Earth. (Given: mass of the Sun, $M_{s} = 4 \times 10^{31}$ kg, mass of moon, $M_{m} = 6.3 \times 10^{22}$ kg, distance between the Sun and the Earth, $r = 1.3 \times 10^{12}$ m and the distance between moon and the Earth, $r = 4.5 \times 10^{8}$ m).
