Question

The force of attraction between two bodies of masses 1 gram each separated by
a distance of 1 metre is
​

Answer 1

The force ofgravitation between two bodies of mass 1kg each separated by a distance of 1 m in vacuum is:

A .

6.67×10−9N

B .

6.67×10−10N

C .

6.67×10−11N

D .

6.67×10−12N

ANSWER

F=r2Gm1m2

   =(1)26.67×10−11×1×1

   =6.67×10−11N

Answer 2

Answer :   6.6×10⁻¹⁷

Explanation: (G=6.6×10⁻¹¹, m₁ =1×10⁻³Kg, m₂=1×10⁻³Kg)

                       ( F=Gm₁m₂÷r²)

           

              F= Gm₁m₂÷r² =6.6×10⁻¹¹×1×10⁻³×1×10⁻³÷1² =6.6×10⁻¹⁷ N
