The figure shows elliptical orbit of a planet m about the sun S. the shaded area SCD is twice the shaded area SAB. If `t_(1)` be the time for the planet to move from C to D and `t_(2)` is the time to move from A to B, then:

A

`t_(1)=t_(2)`

B

`t_(1)=8t_(2)`

C

`t_(1)=4t_(2)`

D

`t_(1)=2t_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
From kepler's law areal velocity = constant so `("area "SCD)/(t_(1))=("area "SAB)/(t_(2))impliest_(1)=2t_(2)`

A planet of mass m is moving in an elliptical orbit about the sun (mass of sun = M). The maximum and minimum distances of the planet from the sun are r_(1) and r_(2) respectively. The period of revolution of the planet wil be proportional to :

A particle is projected vertically upwards from a point A on the ground. It takes t_(1) time to reach a point B but it still continues to move up. If it takes further t_(2) time to reach the ground from point B then height of point B from the ground is :-

In the picture below the planet orbits around the sun with a period of 40 months and takes 12 months to translate from the point D to point E and 1 month from point B to C. the area of the ellipse is A. mass of the satellite. Q. The area of the shaded region

In the Rutherford’s nuclear model of the atom, the nucleus (radius about 10^(–15) m) is analogous to the sun about which the electron move in orbit (radius ~~ 10^(–10) m) like the earth orbits around the sun. If the dimensions of the solar system had the same proportions as those of the atom, would the earth be closer to or farther away from the sun than actually it is? The radius of earth’s orbit is about 1.5 xx 10^(11) m. The radius of sun is taken as 7 xx 10^8 m .

An object is thrown upwards with an initial velocity of 17 m/sec from a building with 12 m height. It is at a height of S = 12 + 17t – 5t^(2) from the ground after a flight of ‘t’ seconds. Find the time taken by the object to touch the ground.
