- Escape velocity of a satellite of the earth at an altitude equal to radius of the earth is v. What will be the escape velocity at...
- If g is the acceleration due to gravity and R is radius of earth, the minimum kinetic energy required to make a satellite to move...
- If the earth suddenly contracts so that its radius reduces by 4% with mass remaining same, then what will happen to the escape...
- If two identical satellites are at R and 7R away from earth surface, the wrong statement is (R = Radius of earth)
- Planet A has a mass and radius twice that of planet B. The escape velocity from planet A is
- The moon revolves around the earth in a circular orbit of radius 3.84 10^ 5 km with velocity 1 km/s. The additional velocity...
- The value of 'g' at a certain height h above the free surface of Earth is x 4 where x is the value of 'g' at the surface of...
- The mass of the moon is 1 81 of the earth but the gravitational pull is 1 6 of the earth. It is due to the fact that
- R is the radius of the earth and is its angular velocity and g_p is the value of g at the poles. The effective value of g at the...

- Assuming the earth as a sphere of uniform density, the acceleration due to gravity half way towards the centre of the earth will...
- If the change in the value of 'g' at a height h above the surface of the earth is the same as at a depth x below it, then (both x...
- The value of 'g' at a certain height above the surface of the earth is 16% of its value on the surface. The height is (R = 6300...
