Determine the escape velocity of a body from the moon. Take the moon to be a uniform sphere of radius 1.76 xx 10^(6) m , and mass 7.36 xx 10^(22) kg . Given G=6.67 xx 10^(-11) Nm^(2) kg^(-2)

The radius of the moom is 1.7 xx 10^(6) m and its mass is 7.4 xx 10^(22) kg . If G = 6.67 xx 10^(-11) Nm^(2) kg^(-2) , find the value of acceleration due to gravity on the surface of moon.

The radius of the earth is 6.37 xx 10^(6) m and its mean density is 5.5 xx 10^(3) "kg m"^(-3) and G = 6.67 xx 10^(-11) "N-m"^(2) kg^(-2) Find the gravitational potential on the surface of the earth.

Determine the gravitational potential on the surface of earth, given that radius of the earth is 6.4 xx 10^(6) m : its mean density is 5.5 xx 10^(3)kg m^(-3) , G = 6.67 xx 10^(-11) Nm^(2) kg^(-2) .

The mass of the earth is 6 xx 10^(24) kg. The distance between the earth and the sun is 1.5 xx 10^(11) m. If the gravitational force between the two is 3.5 xx 10^(22) N, what is the mass of the Sun ? Use G = 6.7 xx 10^(-11) N.m^(2) kg^(-2) gt

When a force is applied on a wire of uniform cross-sectional are 3 xx 10^(-6) m^(2) and length 4 m, the increase in length is 1 mm. Energy stored in it will be (Given, Y = 2 xx 10^(11) Nm^(-2) )

3 times 8+6 times 11+9 times 14+..........

G = 6.67 xx 10^(-11) kg^(-1) m^(3) s^(-2) . Convert it into CGS system.

The period of moon around the earth is 27.3 days and radius of the orbit is 3.9 xx 10^(5) km . G=6.67 xx 10^(-11) Nm^(-2)kg^(-2) , find the mass of the earth.

The mean radius of a planet is 6.67xx10^(3) km. The acceleration due to gravity on its surface is 10 m//s^(2) . If G = 6.67xx10^(-11)Nm^(2)//kg^(2) , then the mass of the planet will be [R=6.67xx10^(6)m]
