Gravitation Tes...

Correct form of gravitational law is:

The mass and radius of moon are $$7.4 \times {10^{22}}kg$$   and $$17.4 \times {10^{6}}kg$$   . Find the acceleration due to gravity at the moon .$$(G = 6.67 \times {10^{ - 11}}N{m^2}k{g^{ - 2}})$$

A  mass of 3 kg is dropped from a tower of 125m high. After 3s its K.E. will be :-

$$g_e$$ and $$g_p$$ denote the acceleration due to gravity on the surface of earth and another planet whose mass and radius are twice that of the earth, then

A mass of 1kg on earth weighs ( 1/6) kg on moon. The radius of the moon is $$1.738\times 10^{6}$$m. The mass of the moon is ( g$$_{e}=9.8m/s^{2},G=6.67\times 10^{-11}Mn^{2}/kg^{2}$$)

The tilt of Earth is _____ degrees.

The density of cooking oil is $$0.6g/c{m^3}$$ What is the mass of $$18c{m^3}$$ of the cooking oil?

Newton's law of gravitation:

The mass of body is measured to be $$12$$ $$ kg$$ on earth. If it is taken to the moon, then its mass will be

The value of universal gravitational constant on earth for a particle of mass 5 kgs is
