Below are four equations expressing relationships between qualities. 'g' gravitational field strengths, r radius , rho a density, G the universal constant of gravitational, m a mass and T a time period. Which of the equations are true. (a) g T^(2) = 4pi r^(2)(b) (4)/(3) pi rho G r^(2) = g (c) g r^(2) = Gm(d) g = (4)/(3) pi rho Gr
