SI unit of Gravitional Constant |
| Answer» F = Gm₁m₂/r²consider two bodies of mass m1 and m2 separated by distance r then force is directly proportional to the product of massses and inversly proportional to the square of distance b/w them after removing the proportionality we get a contant universal gravitational constants.i. units we can rearrang the formula toG = Fr²/ m₁m₂si units of force = N (newton) , r= m (meters)mass = kg (kilograms)substituting in the above eqn we getunits of G = Nm²/kg² or Nm²kg⁻²also dimensional formula = [M⁻¹L³T⁻²] | |
