Gravitational acceleration at moon is 1/6 of that on earth. On earth, if an object floats in water with fraction 'fe' of its volume submersed in water, and on moon, fraction 'fm' is submersed, then
fe = fm
For a floating object, its weight equals the weight of the water it displaces. Since both the object's weight and the buoyant force are proportional to the same value of 'g', the acceleration due to gravity cancels out of this balance, leaving the submerged fraction dependent only on the ratio of the object's density to water's density. Therefore the submerged fraction is the same on the Moon as on Earth, so fe equals fm.
The acceleration due to gravity at the Earth's surface depends on
For which one of the following does the centre of mass lie outside the body?
An object weighs 9 N on the surface of the Earth. What would be its weight, when measured on the surface of a planet where the acceleration due to gravity is 9 times that on the surface of the Earth?
Which of the following statement is correct?
I. Gravitation is a weak force unless large masses are involved.
II. The weight is equal to the product of mass and acceleration due to gravity.
What is the reason that the value of g (acceleration due to gravity) becomes greater at the poles than at the equator?
If the acceleration due to gravity on the surface of earth is g, then the acceleration due to gravity on the surface of a planet whose mass is same as that of earth and radius is twice as that of earth is ___________.
A man's mass is 72 kg on the earth. His mass on the moon will be:
At which of the following place, weight of an object is maximum?
