16. Calculate the force of gravitation between the earth and the
Sun, given that the mass of the earth = 6 x 1024 kg and of the
Sun = 2 x 1030 kg. The average distance between the two is
1.5 x 1011 m.

Q3) My pitch keeps fluctuating. How can I make my voice stable ? The most significant aspect of Beethoven’s character was that
(i) he resigned to his disability and made peace with his situation.
(ii) he took to painting to keep his creative skills intact.
(iii) he retreated to observing nature and enjoying its bounty.
(iv) he fought against his disability in a constructive way and continued composing music.
Answer:
M1 = Mass of the Sun = 2 × 10^30 kg
M2 = Mass of the Earth = 6 × 10^24 kg
R = Average distance between the Earth and the Sun = 1.5 × 10^11 m
G = 6.7 × 10^−11 Nm^2 kg^−2
According to the universal law of gravitational,
F = G× M1 × M2/ r^2
(Put the values of all quantities, we get)
=6.7×10^−11×2×10^30×6×10^24/(1.5×10^11)^2
= 3.57 × 10^22 N
Hence, the force of gravitation between the Earth and the Sun is
3.57 × 10^22 N
