Two planets "A" and "B" revolve around the same sun in different circular orbits.If `m_(A)` : `m_(B)`=`1:2` and `T_(A):T_(B)`= `8:1`. Where `m_(A)`,`m_(B)` are the masses and `T_(A)`,`T_(B)` are the time periods of planets "A" and "B" respectively.The ratio of angular momentum of planet "A" and planet "B" about their common sun is

The distance of two planets from the sun are 10^(13) and 10^(12) m respectively. The ratio of the periods of the planet is

A system of binary stars of mass m_(A) and m_(B) are moving in circular orbits of radii r_(A) and r_(B) respectively. If T_(A) and T_(B) are at the time periods of masses m_(A) and m_(B) respectively then

A planet is revolving around the sun. its distance from the sun at apogee is r_(A) and that at perigee is r_(p) . The masses of planet and sun are 'm' and M respectively, V_(A) is the velocity of planet at apogee and V_(P) is at perigee respectively and T is the time period of revolution of planet around the sun, then identify the wrong answer.

A planet is revolving around the sun in a circular orbit with a radius r. The time period is T .If the force between the planet and star is proportional to r^(-3//2) then the quare of time period is proportional to

The distance of the two planets from the Sun are 10^(13)m and 10^(12) m , respectively. Find the ratio of time periods of the two planets.

A planet is moving round the sun in an elliptical orbit as shows. As the planet moves from A to B

Two satellites A and B of masses m_(1) and m_(2)(m_(1)=2m_(2)) are moving in circular orbits of radii r_(1) and r_(2)(r_(1)=4r_(2)) , respectively, around the earth. If their periods are T_(A) and T_(B) , then the ratio T_(A)//T_(B) is

Many planets are revolving around the fixed sun in circular orbits of different radius (R) and difference time period (T) To estimate the mass of the sun the orbital radius (R) and time period (T) of planets were noted. Then "log"_(10) T v/s "log"_(10)R curve was plotted. The curve was found to be approximately straight line (as shown in) having y intercept =6.0 (Neglect the gravitational interaction among the planets) [Take G = (20)/(3) xx 10^(-11) in MKS, pi^(2)= 10 ] The slope of the line should be .

Supose a planet is revolving around the sun in an elliptical path given by (x^(2))/(a^(2)) + (y^(2))/(b^(2))=1 Find time period of revolution Angular momentum of the planet about the sun is L .

In the figure shown a planet moves in an elliptical orbit around the sun. Compare the speeds, linear and angular momenta at the points A and B .
