Universal Law of Gravitation

Find the dimensions of Gepsilon_(0) (G = Universal Gravitational constant, epsilon_(0)= permitivity in vaccum).

Find the minimum radius for a planet of mean density rho and temperature T which can detain oxygen in its atmosphere. ( M_(0)= Molecular weight of Oxygen and G= Universal Gravitational constant)

Two particles of masses 'm' and '9m' are separated by a distance 'r'. At a point on the line joining them the gravitational field is zero. The gravitational potential at that point is (G = Universal constant of gravitation)

In Newton's inverse square law of gravitation had some dependence of radial distance other than r^(-2) which on of kepler's three laws of planetary motion would unchanged ?

Law of gravitation was discovered by Newton and principle of intertia by Galileo. Laws of photoelectric effect were discovered by Einstein and laws of electromagnetic induction by Faraday. Neutron was discovered by J.J. Thomson and electron was discovered by James Chadwick.

STATEMENT-1: Dimensional constants are the quantities whose values are constant STATEMENT-2: Dimensional constants are dimensionless STATEMENT-3 Universal gravitational constant (G) is a dimensional constant

A hypothetical planet in the shape of a sphere is completely made of an incompressible fluid and has a mass M and radius R. If the pressure at the surface of the planet is zero, then the pressure at the centre of the planet is [G = universal constant of gravitation]
