Question

What will be the formula of the mass in terms of g, R and G? (R = radius of the earth)​

Answer 1

Answer:

g = Gm/r^2

universal gravitational contatant

Answer 2

➪Solution:-

➞ Let M be the mass of body, it is placed on a body of mass M,radius R and Centre O. if acceleration due to gravity is G and density of spherical body is uniform such that its mass can be supposed to be concentrated at its Centre O.

➞ Let F the force of attraction between body of mass m and spherical body of mass M.

➞According to Newton's law of gravitation

• F = GMm/R^2

➞ From gravity pull F = mg

mg = GMm/R^2 or g= GM/m^2

∴ M = gR^2/G

∴The formula of the mass in terms of g, R and G will be M=gR^2/G!
