Mass of mars is `6.42xx10^(29)` kg and mass of the sun is `1.99xx10^(30)kg`. What is the total mass?

Mass of earth is (5.97 xx 10 ^(24)) kg and mass of moon is (7.35 xx 10 ^(22)) kg. What is the total mass of the two ?

The mass of planet Jupiter is 1.9xx10^(7)kg and that of the Sun is 1.9x10^(30)kg . The mean distance of Jupiter from the Sun is 7.8xx10^(11) m. Calculate te gravitational force which Sun exerts on Jupiter. Assuming that Jupiter moves in circular orbit around the Sun, also calculate the speed of Jupiter G=6.67xx10^(-11)Nm^(2)kg^(-2) .

Calculate the force of gravitation between the earth the sun, given that the mass of the earth =6xx10^(24) kg and mass of the sun =2xx10^(30) kg. The average distance between the two is 1.5xx10^(11)m .

Calculate the force of attraction between the earth and the sun, given that mass of earth is 6xx10^(24) kg abd mass of sun =2xx10^(30) kg. the average distance between the two is 1.5xx10^(11)m.

The earth revolves round the sun due to gravitatinal attraction. Suppose that the sun and the earth are point particle with their existing masses and that Bhor's quantization rule for angular monentum is valid in the case of gravitation (a) Calculate the minimum radius the earth can have for its orbit. (b) What is the value of the principle quantum number n for the present radius ? Mass of the earth = 6.0 xx 10^(24) kg, mass of the sun = 2.0 xx 10^(30) kg, earth-sun distance = 1.5 xx 10^(11)m .

Calculat the binding energy of the - sum system . Mass of the earth =6xx 10 ^(24) kg , mass of the sun = 2 xx 10^(30) kg, distance between the earth and the sun = 1.5 xx 10^(11) and gravitational constant = 6.6 xx 10 ^(-11) N m^(2) kg^(2)

The mass of sun is 2xx10^(30) kg and mass of earth is 6xx10^(24) kg. if the distance between the centers of sun and earth is 1.5xx10^(8) km, calculate the force of gravitation between them.

Calculate the speed of Jupiter if the mass of Jupiter is 1.9 xx 10^(27) kg . Distance from the sun is 7.8 xx 10^(11)m and the mass of the sun is 2 xx 10^(30) kg .
