Determine the dimension of gravitational constant .

Give the dimension of gravitational constant.

The distance between the centres of two spheres of masses 50 kg and 10 kg is 30 cm. The mutual force of attraction between them is equal to the weight of a body of mass 1/(28) mg. Determine the value of the gravitational constant.

What is the dimension of gravitational intensity ?

The dimension of resistance is

Two lead spheres are kept at a distance of 30 cm . The mass of each sphere is 100 kg. The mutual force of gravitational attraction between them is equal to the weight of a mass of 0.75 mg. Determine the gravitational constant .
