Name the scientist who explained the motion of planets on the basis of gravitational force between the sun and planets.
What name has been given to the force with which two objects lying apart attract each other ?
What happens to the gravitational force between two objects when the distance between them is :
(1) doubled ?
(2) halved ?
The masses of the earth and moon are 6 × 1024 kg and 7.4 × 1022 kg, respectively. The distance between them is 3.8 × 105 km. Calculate the gravitational force of attraction between the two?
Use G = 6.7 × 10–11 N m2 kg–2
Write proper answer in the box:
If `"F" = ("G""m"_1"m"_2)/"d"^2` then F = ______
The value of quantity G in the formula for gravitational force:
In the relation F = G ✕ M ✕ m/d2, the quantity G:
An apple of mass 100 g falls from a tree because of gravitational attraction between the earth and the apple. If the magnitude of force exerted by the earth on the apple be F1 and the magnitude for force exerted by the apple on the earth be F2, then :
If the distance between two masses is doubled, the gravitational force between them becomes less than the previous force.
