Question

12. Calculate the force of gravitation between the Earth and the Sun.
Given that the mass of the Earth = 6 x 10 kg and mass of the Sun = 2 x 1030kg. The average distance
between the two is 1.5 x 10m.
a- 3.57 x 10^22 N
b- 3.52 x 10^22 N
3.57 x 10^-22 N
d- 3.52 x 10^-22 N​

Answer 1

Correct question :

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.

ANSWER -

Given :

• Mass of Earth (Mₑ ) = 6×10²⁴ kg
• Mass of Sun (Mₛ) = 2×10³⁰ kg
• Distance between Earth and Sun(r) = 1.5×10¹¹ m

To find :

Gravitational force between Earth and Sun

Formula used :

$\sf F_g = \dfrac{ G \times M_e \times M_s }{r^2}$

Here,

• F₉ = Gravitational force
• G = Universal Gravitational's constant
• Mₑ = mass of Earth
• Mₛ = mass of Sun
• r = distance between Earth and Sun

Solution :

$\sf \implies \: F_g \: = \dfrac{6.67 \times {10}^{ - 11} \times 2 \times {10}^{30} \times 6 \times {10}^{24} }{ {(1.5 \times {10}^{11}) }^{2} } \\ \\ \\ \sf \implies \: F_g \: = \dfrac{80.04 \times {10}^{(24 + 30 - 11)} }{2.25 \times {10}^{22} } \\ \\ \\ \sf \implies \: F_g \: = 35.57 \times {10}^{(43 - 22)} \\ \\ \sf \implies \: F_g \: = 3.557 \times {10}^{22} \: N$

ANSWER :

Force of gravitation between Earth and Sun = 3.557 × 10²² N
