The value of 'g' does not depend upon mass of the body, but gravitational pull of earth depends on mass of the body, comment.

Text Solution

Verified by Experts

Both the statements are true.
This is because `g=(GM)/R^(2)`,g does not depend upon mass (m) of the body.
Gravitational pull on the body,
`F=mg=m(GM)/R^(2)` clearly, `F prop m`

    The escape velocity of a body does not depend on the mass of the body.

    The escape velocity of a body does not depend on the mass of the body.

    Everybody, when free, falls towards the centre of earth with an acceleration = g , which is called acceleration due to gravity. The value of g on the surface of earth is, g = (GM)/(R^(2)) = 9.8 m//s^(2) . It is a vector, directed always the centre of earth. The value of g does not depend upon shape, size or mass of the body. Rether, it depends on mass and size of earth (or planet due to which there is a gravity pull). Read the above passesge and answer the following questions : (i) A piece of stone and a feather are dropped together in space from the same height. which one will strike the ground first ? (ii) The mass of a planet is (1)/(8)th the mass of earth and its diameter is (5)/(6) the diameter of earth. What is the value of 'g' on the surface of this planet. (iii) What does the concept of free fall imply in day to day life?
