Gravitation Tes...

Two particles of mass $$m_1$$ and $$M_2$$, approach each other due to their mutual gravitational attraction only. Then

Dimensional formula of universal gravitational constant $$G$$ is-

Suppose that you have a mass of $$70\ kg$$. How much mass must another object have in order for your body and the other object to attract each other with a force of $$1
\ N$$ when separated by $$10\ m$$?

If earth's radius were to hypothetically shrink by $$1\%$$, the value of $$G$$ would:

The relationship between acceleration due to gravity($$g$$) and universal gravitational constant($$G$$) may be represented as:
($$M$$ and $$R$$ are the mass and radius of the earth respectively )

How the gravitational constant will change if a brass plate is introduced between two bodies?

The moon's radius is $$\dfrac{1}{4}$$ that of the earth and its mass is $$\dfrac{1}{80}$$ times that of the earth. If $$g$$ represents the acceleration due to gravity on the surface of the earth, that on the surface of the moon is 

An astronaut on a strange planet finds that acceleration due to gravity is twice as that on the surface of Earth. Which of the following could explain this?

Which of the following hypotheses was made by Newton?

A bodyweight $$5 N$$ in the air and $$2 N$$ when immersed in a liquid. The buoyant force is:
