What happens to the force between two objects, if the mass of one object is doubled?
The gravitational intensity at the centre of a hemispherical shell of uniform mass density has the direction indicated by the arrow (see Fig 8.12) (i) a, (ii) b, (iii) c, (iv) 0.
How does the force of gravitation between two objects change when the distance between them is reduced to half?
Write the formula to find the magnitude of the gravitational force between the earth and an object on the surface of the earth.
If you compare the gravitational force on the Earth due to the Sun to that due to the Moon, you would find that the Sun’s pull is greater than the Moon’s pull. (You can check this yourself using the data available in the succeeding exercises). However, the tidal effect of the Moon’s pull is greater than the tidal effect of Sun. Why?
