The value of gravitational constant, G is

Question

The value of gravitational constant,

G

Options:

A . 9.8 m s−2

B . 6.7 N

C . 6.7×10−11 Nm2kg−2

D . 6.7×10−11 Nm2kg2

Answer: Option C
:
C

G

is universal gravitational constant. Its value remains constant everywhere in the universe and gravitational force between bodies

m

and

M

separated by distance

r

is given by:

F = \frac{G M m}{r^{2}}

\Rightarrow G = \frac{F r^{2}}{M m}

∴

Units of G are

N m^{2} k g^{- 2}

The value of Gravitational constant is

6.7 \times 10^{- 11} N m^{2} k g^{- 2}
