Q. Length is measured in metre and time in second as usual. But a new unit of mass is so chosen that $G = 1$. This new unit of mass is equal to
A) $1.5 \times 10^{7}$kg
B) $1.5 \times 10^{10}$kg
C) $6.67 \times 10^{- 11}$kg
D) $6.67 \times 10^{- 8}$kg
Explanation
New unit of mass is $\frac{1}{6.67 \times 10^{- 11}}\$kg $ie,$1.5$\times 10^{10}$ kg.
