Select the correct option:

$\frac{2}{9} \mathrm{~F}$

$\frac{16}{9} \mathrm{~F}$

$\frac{8}{9} \mathrm{~F}$

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

$\begin{aligned} & F=\frac{G m^2}{r^2} \\ & F^{\prime}=\frac{G\left(\frac{4 m}{3}\right) \times\left(\frac{2 m}{3}\right)}{r^2} \\ & F^{\prime}=\frac{8}{9} F\end{aligned}$
