Question

The force of gravitation between two bodies of mass 1 kg each separated by a distance of 1 m in vacuum is ____________.

विकल्प

• 6.67 x 10^-9 N

• 6.67 x 10^-10 N

• 6.67 x 10^-11 N

• 6.67 x 10^-12 N

Answer 1

The force of gravitation between two bodies of mass 1 kg each separated by a distance of 1 m in vacuum is 6.67 x 10^-11 N.

Explanation:

m₁ = m₂ =1 kg, r = 1 m,

`"F" = "G" ("m"_1 xx "m"_2)/"r"`

`= 6.67 xx 10^-11 xx "m"^2/"r"^2`

`= 6.67 xx 10^-11 xx (1/1)^2`

`= 6.67 xx 10^-11  "N"`
