Question

The gravitational force of attraction between two bodies of masses

40 k g

and

80 k g

separated by a distance of

15 m

is:
(Take Gravitational constant,

G = 6.673 \times 10^{- 11} N m^{2} k g^{- 2}

)

Options:

A . 9.49×10−10 N

B . 8.49×10−10 N

C . 7.49×10−10 N

D . 6.49×10−10 N

Answer: Option A
:
A
Given:
mass of first body

m_{1} = 40 k g

mass of second body

m_{2} = 80 k g

distance between two bodies,

R = 15 m

G = 6.673 \times 10^{- 11} N m^{2} k g^{- 2}

Acc. to Newton's law of gravitation, Gravitational force,

F = \frac{G m_{1} m_{2}}{R^{2}}

So,

F = \frac{6.673 \times 10^{- 11} \times 40 \times 80}{15^{2}}

On solving, we get

F = 9.49 \times 10^{- 10} N
