Easy
Who formulated the Universal Law of Gravitation?
Easy
What is the value of the acceleration due to gravity (g) near the surface of the Earth?
Medium
If the radius of the Earth were doubled while its mass remained the same, what would be the new acceleration due to gravity on its surface?
Medium
The gravitational force between two objects is F. If the distance between them is tripled and the mass of one object is doubled, what is the new force?
Medium
What is the escape velocity from the surface of the Earth?
Easy
Which of the following is NOT a consequence of the Universal Law of Gravitation?
Hard
Derive the expression for the acceleration due to gravity (g) on the surface of a planet of mass M and radius R.
Medium
A satellite is orbiting the Earth at a height equal to the radius of the Earth. What is the acceleration due to gravity at that height?
Hard
The gravitational potential at a point outside a spherical mass M at distance r from its center is given by:
Medium
If the mass of the Earth were reduced to half but its radius remained the same, what would be the effect on the weight of an object on its surface?
