Yes, Newton’s third law of motion holds good for the force of gravitation. This means that when earth exerts a force of attraction on an object, then ...
(a) The falling of a body from a height towards the earth under the gravitational force of the earth (with no other forces acting on it) is called fre...
This is the acceleration produced by the earth. It is also called acceleration due to gravity. g = where, G = gravitational constant M = mass ...
(a) One-sixth (b) Mass (c) Six times (d) One-sixth (e) Six times (f) 36N
(a) True (b) False (c) False (d) False (e) False
Weight of the body on the surface of moon will be 1N approx. as the value of g on the surface of moon is one-sixth that of the earth.
Weight, W= m x g = 50 x 9.8 = 490 N
Its weight will be zero as value of g is zero at the centre of the earth.
Weight, W = m x g 50 = m x 9.8 m = 5 gm
Weight, W = m x g = 10 x 9.8 = 98 N
Its weight varies; mass of an object is constant.
Weight of the body varies with altitude; mass of an object is constant.
The weight of a body is directly proportional to its mass. It also depends on the acceleration due to gravity which varies from place to place.
Weight, W = m x g = 1 kg x 9.8 m/s2 = 9.8 N
Gravitational force of the sun holds the solar system together.
Gravitational force (exerted mainly by the moon and to some extent by the sun) is involved in the formation of tides in the sea.
Gravitational force causes two objects lying apart attract each other.
Gravitational force is responsible for the earth revolving round the sun.
The gravitational force F between two bodies of masses M and m kept at a distance d from each other is F = Here, Gravitational constant, G = 6.7 ...
Gravitational force of the earth.
