Question

find the order of magnitude of mass of sun where mass of sun is 1.991×10^30 kg​

Answer 1

Answer:

Mass of sun = 1.99 x 10³⁰ kg. Mass of Earth = 5.97 x 10²⁴kg. Distance between Earth and Sun = 1.49 x 10¹¹m. Gravitational constant (G) = 6.67 x 10⁻¹¹ Nm²/kg²

Answer 2

Answer:

We can use Newton’s law of universal gravitation.

Which is F = Gm1m2/r^2

Where the Force (F) will be in Newtons.

G is the “Universal Gravitational Constant”. G = 6.67 × 10^-11 N m^2 kg^-2

M1 is the first mass, the Sun. Mass of the Sun = 2 x 10^30 kg

M2 is the second mass, the Earth. Mass of the Earth = 6 x 10^24 kg

DR is the distance between the two objects. Distance from the Earth to the Sun = 1.5 x 10^11 metres

F = Gm1m2/r^2

F = G x 2 x 10^30 x 6 x 10^24/ [1.5 x 10^11] ^2 = 6.7 x 10^11 N
