Answer the following :
If you compare the graviational 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. However, the tidal effect to the Moon's pull is greater than the tidal effect of the Sun. Why ?

Text Solution

Verified by Experts

The tidal effect depends inversely on the cube of the distance, while gravitational force depends on the square of the distance.
