Calculate the force of gravitation between two objects of masses $10 \; kg$ and $20 \; kg$ at a distance of $10 \; m$ from each other. $\left[G = 6.67 \times 10^{-11} \; Nm^2 kg^{-2}\right]$

• A
  $6.67 \times 10^{-10} \; N$
• B
  $13.34 \times 10^{-11} \; N$
• C
  $1.334 \times 10^{-11} \; N$
• D
  $26.68 \times 10^{-10} \; N$
