The moon subtends an angle of 57 minutes at the base line equal to radius of earth. What is the distance of moon from earth. Given radius of earth is 6400 km.

The Moon subtends an angle of 1^(@) 55' at the base line equal to the diameter of the Earth. What is the distance of the Moon from the Earth? (Radius of the Earth is 6.4 xx 10^(6) m)

The moon subtends an angle of 57 minutes at two diametrically opposite points on earth. Calculate the distance of the moon from the earth. Given, diameter of earth =1.276xx10^7 m .

At what height above the surface of the earth is the gravitational potential energy of a body equal to that on the surface of the moon ? Assume that the mass of the earth is 80 times that of the moon and the radius of the earth is 4 times that of the moon. Given ,Radius of the earth =6400 km.

Assuming that the earth’s radius is 6400 km and that it subtends an angle of 57’ at the centre of the moon, find the distance of the centre of the moon from the earth’s centre.

A body weighs 63 N on the surface of the Earth . What is the gravitational force on it due to the Earth , at a height equal to half the radius of the Earth ? (Given that the radius of Earth = 6400 km).

The radius of the earth 6400 km and moon's distance from the earth is 60 times , the radius of earth , if the radius of the moon subtends 16' angle at the centre of the earth ,find the diameter of the moon.

From two diametrically opposite points A and B on earth, moon is observed. The angle theta subtended at the moon by the two directions of observation is 1^@ 54^1 . If radius of earth is 0.638 xx 10^7 m, find the distance of the moon from the earth.
