Newton’s law of Gravitation

there is a force of attraction between any two massive particles in the universe, which is known as gravitational force or force of gravity. Magnitude of this force is proportional to the product of masses of the particles and inversely proportional to the square of distance between them.”

     Let two particals m1 and m2 ,and distance between ‘r’ than gravitational force  ‘F of magnitude,

                          F=Gm1m2/r^2

Where, 

                G= universal gravitational constant

Universal gravitational constant——–

                       F=Gm1m2/r^2

                         m1=m2=1 kg

                      r=1 meter

          Then,.   G=F

SI unit of ‘G’.        

                              Newton Metre^2/kg^2

                 Value of ‘G’.    6.67×10^-11

• Cloud Black Hole Energy Save Humanity’s FutureDecember 22, 2022
  IN BRIEF One day the sun will fail. The fuel powering its nuclear fusion will run out, the sky will grow cold and, if Earth survives at all, humankind will be plunged into perpetual winter. To stay alive, our descendants will need to make alternative arrangements. They will first exhaust the resources of Earth, then the solar system, and eventually all the stars in… Read more: Cloud Black Hole Energy Save Humanity’s Future
