In a new system of units energy, density and power are taken as fundamental units, then the dimensional formula of universal gravitational constant G will



According to newton`s law of gravitation,
force = G×mass²/distance²
so G = (force×(distance²))/(mass²)
dimensional formula of G ={( MLT⁻²)×L²}/M² = M⁻¹L³T⁻²
dimensional formula of energy(E) = ML²T⁻²
dimensional formula of density(D) = ML⁻³
dimensional formula of power (P) = ML²T⁻³
  SO dimensional formula of G in terms of E,D,P will b = D⁻¹P²E⁻²
