★Calculate the gravitational force if mass of one object is 7.3×1e9 kg and mass of another object 2.4×1e20 kg and distance between them is 4×10 km.

${ \huge{ \blue{ \underline{SOLUTION : }}}}$

${ \large{ \red{ \boxed{ \green{G ravitational \: Force = \frac{ Gravtational \: constant \times \: product \: of \: mass \: of \: objects}{ {(distance \: between \: the \: objects)}^{2} } }}}}}$

$F = \frac{6.67\times {10}^{( - 11)} \times 7.3 \times {10}^{9} \times 2.4 \times {10}^{20} }{ {(4 \times {10}^{3} )}^{2} } \\ \\ \\ \\ F = \frac{6.67 \times 7.3 \times 2.4 \times {10}^{ (- 11 + 9 + 20)} }{16 \times {10}^{6} } \\ \\ \\ \\ F = \frac{ 116.86 \times {10}^{(18 - 6)} }{16} \\ \\ \\ \\ F = \frac{ \cancel{116.86} \times {10}^{12} }{ \cancel{16}} \\ \\ \\ \\ { \huge{ \pink{ \boxed{F = 7.3 \times {10}^{12} N}}}}$

The Gravitational force working between both the objects is 7.3×10¹² Newton.

More Information:–

• According to Newton, every object in the universe attract each-other with a force. This force of attraction is called gravitational force.
• Gravitational force of Earth is called gravity.
