A) \[\text{6}.\text{67}\times \text{1}{{0}^{-\text{13}}}\text{ N}\]
B) \[\text{6}.\text{67}\times \text{1}{{0}^{-11}}\text{ N}\]
C) \[\text{6}.\text{67}\times \text{1}{{0}^{-\text{7}}}\text{ N}\]
D) \[\text{6}.\text{67}\times \text{1}{{0}^{-4}}\text{ N}\]
Correct Answer: A
Solution :
\[F=\frac{G{{m}_{1}}{{m}_{2}}}{{{r}^{2}}}\] \[=\frac{6.67\times {{10}^{-11}}\times 1\times 1}{{{10}^{2}}}=6.67\times {{10}^{-13}}N\]
