The variation of acceleration due to gravity g with distance d from centre of the earth is best represented by (R=earth 's radius):

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
For `dlt R`,
`g=(GMd)/(R^3)`[g-d graph is linear]
For d=R,
`g=(GM)/(R^2)`[highest value of g]
And for `d gt R`,
`g=(GM)/(d^2)` [g-d graph is a rectangular parabola)
