Question

Calculate the force of gravity between two students with mass 55 kg and
45 kg and they are 1 m away from each other.

Answer 1

$\Huge\boxed{\underline{\underline {\purple{Answer}}}}$

$\large\sf{Given}$:-

• Mass of one student = 55 kg
• Mass of another student = 45 kg
• Distance between them = 1 m

$\large\sf{To\:Find}$:-

Force of gravity between the two students

$\large\sf{Formula \:Used}$:-

$\boxed{F = G \frac{m_{1}m_{2}}{{d}^{2} }}$

• $G = 6.67\times 10^{-11} N kg^{-2}m^{2}$

$\large\sf{Solution}$:-

$\sf{Let}$:-

• Mass of one student $m_{1}$.
• Mass of another student be $m_{2}$
• Distance between the two students be d .

Now, on putting the values in the formula we get :

$F = G \frac{m_{1}m_{2}}{{d}^{2} }$

$\implies F = 6.67\times 10^{-11}\frac{55\times 45}{1^{2}}N$

$\implies F = 16,508.25 \times 10^{-11} N$

$\implies F = 1.650825 \times 10^{-17}N$
