The variation of gravitational field intensity (E ) due to the earth is represented by curve in Fig. (R is radius of earth):

Answer»




SOLUTION :Gravitational field `E=(GM)/(R^(2))=g`
SINCE from centre of earth to surface of earth `g prop r` and above the surface of earth `g prop (1)/(r^(2))`
`therefore` The variation of E is represented by FIG. d.
