The value of G varies from place to place.
पर्याय
Right
Wrong
उत्तर
This statement is Wrong.
Explanation:
The value of a gravitational constant (G) is always the same irrespective of place. However, according to Newton's law of universal gravitation, the acceleration of gravity (g) varies with mass and the distance from its centre.

The weight of an object varies on different planets.
The mass of the moon is `1/81` of the mass of the earth. Its diameter is `1/3.7` of that of the earth. If acceleration due to gravity on the surface of the earth is 9.8 m/s2, then the acceleration due to gravity on the surface of the moon.
The mass of a body on the surface of the earth is 10 kg. The mass of the same body on the surface on the moon is `"g"_"m" = 1/6 "g"_"e"`, where gm, ge acceleration due to gravity on the surface of the moon and the earth respectively.
The acceleration due to gravity on a planet is 1.96 m/s2. If it is safe to jump from a height of 3 m on tbe earth, the corresponding height on the planet will be ____________.
The acceleration due to gravity on moon is `(1/6)^"th"` times the acceleration due to gravity on earth. If the ratio of the density of earth 'ρe' to the density of moon 'ρm' is `5/3`, then the radius of moon 'Rm' in terms of the radius of earth 'Re' is ______.
The radius of the earth is. 6400 km and that of mars is 3200 km. The mass of the earth is about 10 times the mass of mars. Weight of the object on the earth is 200 N. What will be its weight on the mars?
On the earth, a stone is thrown from a height in a direction parallel to the earth’s surface while another stone is simultaneously dropped from the same height. Which stone would reach the ground first and why?
How does the force of attraction between the two bodies depend upon their masses and the distance between them? A student thought that two bricks tied together would fall faster than a single one under the action of gravity. Do you agree with his hypothesis or not? Comment.
The value of gravitational acceleration g at a height h above the earth's surface is `"g"/4`, then ______. (R = radius of earth)
