Answer 1

Answer:

Given:

⟹ Mass of the Earth,m1=6×10²⁴ kg

⟹ Mass of the sun,m2=2×10³⁰kg

⟹ The distance between the sun and earth,

r=1.5×10¹¹m

As we know that,

The force of gravitation between the sun and the earth,

F=Gm1m2/r²

Here,

G=gravitational constant

$gravitational \: constant = 6.67 \times {10}^{ - 11} N {m}^{2} {kg}^{ - 2}$

Now,

Force,

$F = \frac{6.67 \times {10}^{ - 11} \times 12 \times {10}^{54} }{1.5 \times 1.5 \times {10}^{22} }$

$F= \frac{6.67 \times {10}^{21} \times 12}{2.25}$

$F= 3.557 \times {10}^{22}N$
