Question

two bodies having mass 40 kg each are separated by a distance of 2 metre find the gravitational force​

Answer 1

$\huge{\bold{\underline{\underline{....Answer....}}}}$

$\huge{\bold{\underline{Given:-}}}$

$\large{\bold{ \star \: m_1 = 40 \: Kg}}$

$\large{\bold{ \star \: m_2 = 40 \: Kg}}$

$\large{\bold{ \star \: r = 2 \: meters}}$

$\large{\bold{ \star \: G = 6.67 \times 10^{-11} Nm^2/Kg^2}}$

$\huge{\bold{\underline{Explanation:-}}}$

As we know,

$\large{\bold{F = \dfrac{Gm_1m_2}{r^2}}}$

Substituting the values,

$\large{F = \dfrac{6.67 \times 10^{-11} \times 40 \times 40}{(2)^2}}$

$\large{F = \dfrac{6.67 \times 10^{-11} \times 1600}{4}}$

$\large{F = \dfrac{6.67 \times 10^{-11} \times \cancel{1600}}{ \cancel{4}}}$

$\large{F = 6.67 \times 10^{-11} \times 400}$

$\large{F = 2688 \times 10^{-11}}$

$\huge{\boxed{\boxed{F = 2.688 \times 10^{-8} \: N}}}$

So,the Force acting is 2.688 × 10^ - 8 N.

Important points:-

• Gravitational Force is a central force.
• It obeys inverse - Square rule.
• It is also called action and reaction force.
• It is high range force.
• It has a range of about ${ \infty}$.
