Suppose the law of gravitational attraction suddenly changes and becomes an inverse cube law i.e. `F prop 1//r^3` , but still remaining a central force. Then

A

Kepler’s law of areas still holds

B

Kepler’s law of period still holds

C

Kepler’s law of period still holds

D

Neither the law of areas, nor the law of period still holds

Text Solution

Verified by Experts

The correct Answer is:
D
Since, `Fprop1/(r^3)`
Path is not elliptical, hence both law are invalid.

If the law of gravitational, instead of being inverse-square law, becomes an inverse-cube law

Suppose that the gravitational force between two bodies separated by a distance R becomes inversely proportional to R (and not as (1)/(R^(2)) as given by Newton's law of gravitation). Then the speed of a particle moving in a circular orbit of radius R under such a force would be proportional to

If the law of gravitation be such that the force of attraction between two particles vary inversely as the 5//2^(th) powr of their separation then the graph of orbital velocity v_(0) plotted against the distance r of a satellite from the earth's centre on a log-log scale is shown alongside the slope oline will be

The inverse square law of intensity (i.e., the intensity prop1/r^2) is valid for a

Suppose a light planet is revolving around a heavy star in a circular orbit of radius r and period of revolution T. The gravitational force of attraction between the star and the planet is proportional to (1)/(r^(3//2)) . Derive the relation between T and r.

Keller's third law states that the square of period of revolution (T) of a planet around the sun is proportional to the sun is proportional to the third power of average distance , r between the sun and the planet i.e T^2 = Kr^3 Here ,K is constant . If masses of the sun and the planet are M and m respectively , then as per Newton's law of gravitation force of attraction between them is F =(GMm)/r^2 , Where G is gravitational constant . The relation between G and K is described as

STATEMENT-1 : The electrostatic force is much stronger than the gravitational force. STATEMENT-2 : Electrostatic force can be attractive or repulsive. STATEMENT-3 : Electrostatic force is central force.

Statement-1 : Two soild sphere of radius r and 2r , made of same material, are kept in contact. The mutual grvitational force to attraction between them is proportional to 1//r^(4) . Statement-2 : Gravitational attraction between two point mass bodies varies inversely as the square of the distance between them.
