Q. 6

# Find the acceleration due to gravity of the moon at a point 1000 Km above the moon’s surface. The mass of the moon is 7.4 × 10^{22} kg and its radius is 1740 km.

Answer :

The mass of the moon is , radius is

Distance of the point from surface,

Total distance from the center,

We know acceleration due to gravity is given by,

Is it possible for a body to have inertia but no weight?

Physics - ExemplarThe centre of mass of an extended body on the surface of the earth and its centre of gravity

Physics - ExemplarIf the mass of sun were ten times smaller and gravitational constant G were ten times larger in magnitudes -

Physics - ExemplarThe weight of a body at the poles is greater than the weight at the equator. Is it the actual weight or the apparent weight we are talking about? Does your answer depend on whether only the earth’s rotation is taken into account or the flattering of the earth’s at the poles is also taken into account?

HC Verma - Concepts of Physics Part 1A person sitting in a chair in a satellite feels weightless because

HC Verma - Concepts of Physics Part 1A body is suspended from a spring balance kept in a satellite. The reading of the balance is W_{1} when the satellite goes in an orbit of radius R and is W_{2} when it goes in an orbit of radius 2R.

Take the effect of bulging of earth and its rotation in account. Consider the following statement:

(A)There are points outside the earth where the value of g is equal to its value at the equator.

(B)There are points outside the earth where the value of g is equal to its value at the poles.

If heavier bodies are attracted more strongly by the earth, why don’t they fall faster that the lighter bodies?
