Question

what is the force between two sphere of 20 kg each placed at 50cm apart​

Answer 1

SOLUTION:-

$m_{1} = m_{2} = 20 \: kg$

$r = 50 \:cm = 0.5 \: m$

☞︎︎︎we know that ,according to Newton's law of gravitation the force between two masses M1 & M2 which is speed r m apart is ,

$➪ f = \frac{ m_{1}m_{1}}{ {r}^{2} }$

$➪f = 6.67 \times {11}^{ - 11} \: \frac{20 \times 20}{0.5 \times 0.5}$

$➪ \frac{2668}{0.25} \times {10}^{ - 11}$

$➪1.0672 \times {10}^{ - 7}n$
