Question

Find the gravitational force between two object having mass 800 kg and 400 kg respectively and center disease between them is 10 metre

Answer 1

QUESTION :-

▪ Find the gravitational force between two objects having mass 800 kg and 400 kg respectively and distance between them is 10 m?

SOLUTION :-

GIVEN -

▪ mass of first object ( m1 ) = 800 kg

▪ mass of other object ( m2 ) = 400 kg

▪ Distance between the two objects = 10 m

TO FIND -

▪ Gravitational force between the two object??

${ \underline{ \underline { \sf{gravitational \: force}}}}$

${ \boxed{ \sf{F = G \times \frac{m1 \times m2}{ {r}^{2} } }}}$

where,

▪ G = Gravitational constant

${ \sf{ = 6.7 \times {10}^{ - 11} \frac{N \: {m}^{2} }{ {kg}^{2} } }}$

• substituting the above given values in the formula....

${ \sf{F = 6.7 \times {10}^{ - 11} \frac{N \: {m}^{2} }{ {kg}^{2} } \times \frac{800 \: kg \: \times \: 400 \: kg}{ {10 \: m}^{2} } }}$

${ \implies{ \sf{f = 6.7 \times 8 \times 4 \times {10}^{ - 11} \times {10}^{3} \: N}}}$

${ \underline{ \sf{force = 214.4 \times {10}^{ - 8} \: N}}}$
