Question

plz solve this question........

Answer 1

Mass of sun, M = 2 × 10^30 kg

Mass of earth, m = 6 × 10^24 kg

distance between them, R = 1.5 × 10^8 km = 1.5 × 10^11 m

Gravitational force between them =

$\text{ force}= \frac{GMm}{ {R}^{2} } \\ \\ = \frac{6.67 \times {10}^{ - 11} \times 2 \times {10}^{30} \times 6 \times {10}^{24} }{ {(1.5 \times {10}^{11}) }^{2} }\ N$

$= \frac{6.67 \times 2 \times 6 \times {10}^{(30 + 24 - 11)} }{ 2.25 \times {10}^{22}}\ N\\ \\ = \frac{80.04 \times {10}^{43} }{2.25 \times {10}^{22} }\ N$

$= 35.57 \times {10}^{21} \ N \\ \\ = 3.557 \times {10}^{22}\ N$

Gravitational force between earth and sun is 3.557 × 10^22 N
