State whether the following statement is true or false :
The value of G on the moon is about one-sixth `(1/6)`of the value of G on the earth.
Fill in the following blank with suitable word :
The value of g on the earth is about………………. of that on the moon.
Explain why the value of g is zero at the centre of the earth.
The radius of planet A is half the radius of planet B. If the mass of A is MA, what must be the mass of B so that the value of g on B is half that of its value on A?
The value of g is highest at the equator.
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.
When the value of acceleration due to gravity 'g' becomes `(g/3)` above the earth's surface at height 'h' then relation between 'h' and 'R' is ______.
R =radius of the earth
The radius of the orbit of a geostationary satellite is (mean radius of the earth R, angular velocity about an axis in ω and acceleration due to gravity on earth's surface is (g) ______.
The force of attraction between two unit point masses separated by a unit distance is called
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?
Suppose the gravity of the earth suddenly becomes zero, then in which direction will the moon begin to move if no other celestial body affects it?
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.
A central particle M is surrounded by a square array of other particles, separated by either distanced or distance d/2 along the perimeter o the square. The magnitude of the gravitational force on the central particle due to the other particles is ______.
A mass attached to one end of a string crosses top-most point on a vertical circle with critical speed. Its centripetal acceleration when string becomes horizontal will be ______. (g = gravitational acceleration)
A body is thrown from the surface of the earth with velocity 'u' m/s. The maximum height in m above the surface of the earth upto which it will reach is ______.
(R = radius of earth, g = acceleration due to gravity)
A lift of mass 'm' is connected to a rope which is moving upward with maximum acceleration 'a'. For maximum safe stress, the elastic limit of the rope is 'T'. The minimum diameter of the rope is ______.
(g = gravitational acceleration)
The depth 'd' at which the value of acceleration due to gravity becomes `"I"/"n"` times the value at the earth's surface is ______. (R = radius of earth)
If the change in the value of g at the height h above the surface of the earth is the same as at a depth x below it, then ______.
(both x and h being much smaller than the radius of the earth)
A uniform ring of mass M and radius r is placed directly above a uniform sphere of mass 8M and of same radius R. The centre of the ring is at a distance of d = `sqrt3`R from the centre of the sphere. The gravitational attraction between the sphere and the ring is ______.
