The CGS unit of G is dyne.cm2/g2.
The value of G varies from place to place.
As we go above the earth's surface, value of g increases.
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.
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 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?
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)
