Time : 1.30 Hours

Part - A

Generic 2 - Answer All Question

An unknown planet orbits the Sun with distance twice the semi-major axis distance of the Earth’s orbit. If the Earth’s time period is T₁, what is the time period of this unknown planet?

Earth revolves around the Sun at 30 km s⁻¹. Calculate the kinetic energy of the Earth. In the previous example you calculated the potential energy of the Earth. What is the total energy of the Earth in that case? Is the total energy positive? Give reasons.

The figure shows elliptical orbit of a planet 'M' about the Sun'S', the shaded area SCD is twice the shaded area SAB. If t₁. is the time for the planet to move from C and D and t2 is the time to move from A to B then.

By which law is the Kepler's law of areas identical? Is this Kepler's law kinematic?

How will you prove that Earth itself is spinning?

Suppose we go 200 km above and below the surface of the Earth, what are the g values at these two points? In which case, is the value of g small?

The Moon Io orbits Jupiter once in 1.769 days. The orbital radius of the Moon Io is 421700 km. Calculate the mass of Jupiter?

Which model is accepted 'Heliocentric model'? Why?

The mass of a space ship is 1000 kg. It is to be launched from Earth's surface out into free space the value of g and R (radius of Earth) are 10 ms^-2 and 6400 km respectively. The required energy for this work will be.

What is the gravitational potential energy of the Earth and Sun? The Earth to Sun distance is around 150 million km. The mass of the Earth is 5.9 × 10²⁴ kg and mass of the Sun is 1.9 × 10³⁰ kg.
