2 satellite or orbiting around the earth in circular orbits of the same radius the mass of statellight A use 5 times greater than the mass of satellite be there periods of revaluation or in the ratio

• 1:1

• 1:10

• 5:1

• 1:5

If the distance between the Earth and the Sun becomes half of its present value the number of days in a year would have been

• 64.5

• 129

• 182.5

• 730

A satellite in a circular orbit of radius or has been period of 4 hours yes satellite of arbit radium4 hours around them same planet will have period

• 8h

• 16h

• 32h

• 64h

The rotation period of an Earth satellite close to the surface of these 83 minutes the time period of another earth satellite in and orbital distance of 3 Earth radii from its surface will be

• 83 min

• 83×√8 min

• 664 min

• 249 min

Figure shows there elliptical path of a Planet about the sun that two share that part have equal area if T1 and t2 the time taken by the planet to go from a to b and from c to d respectively then

• T1<t2

• T1=t2

• T1>t2

• Insufficient information to diduse the relation between t1 and t2

A satellite to go Salon and elliptical Baat around here the rate of change of Arc length by the satellite is proportional to

• r

• r²

• r^1/2

• r^-1

A comet orbits the sun in a highly elliptical Orbit the comet have a constant

• Angular speed

• Angular momentum

• Potential energy

• Kinetic energy

The law of area is a consequence of the law of conservation of

• Angular momentum

• Linear momentum

• Energy

• Mass

Two particles of equal mass M Go Round yes circle of radius or under the action of their mutual gravitational attraction the speed of each particle is

• V=1/2r √1/Gm

• V=√Gm/2R

• V=1/2√Gm/R

• V=√4Gm/R

Newton's law of gravitation is valid for

• Small bodies only

• Planets only

• Both small and big bodies

• Only valid for solar system
