Gravitational force does not depend on:
The value of ‘g’ is minimum:
The value of 'g' that is gravity is greater at the poles because the gravitational pull is maximum at the poles and decreases as it comes down toward the equator.
Weight of an object is highest at
Apple falls towards the earth but the earth does not move towards the apple because
What is the mass of a body whose weight is 59 N? Take g = 9.8 m/s2
A ball is thrown vertically upwards with a velocity ‘u’. The velocity with which it falls to the earth again is:
Weight of a body on earth is 48 N; its weight on moon is
Universal law of gravitation does not explain
The mass of a body on earth is 60 kg, its mass on moon is
A mass of 60kg on Earth will exert a downwards force (its 'weight') of 60 x 9.8 = 588N. A mass of 60kg on the Moon will still be 60Kg as mass is independent of gravity, but will 'weigh' about 60 x 1.3 = 78N. The Moon's gravity (its gravitational constant) is about 1/6th that of the Earth's.
The value of acceleration due to gravity at the poles
The force of gravitation between two bodies varies with r as:
The magnitude of gravitational force between the earth and 10 kg body is:
If the mass of earth is increased by 25% without any change in its size. Then, its acceleration due to gravity:
The acceleration due to gravity on earth is given by g = GM/R^2.
From the above equation, we observe that acceleration is directly proportional to the mass of the earth. So, if the mass of the earth is increased by 25 % and R is kept constant, the value of g will also increase by 25%.
Which of following is not related to gravitational law?
How much gravitational force acts between two people of mass 60 kg each sitting at distance of 1 m apart?
