The value of g on the earth's surface is...

The value of `g` on the earth's surface is `980 cm//sec^(2)` . Its value at a height of `64` km from the earth's surface is

A

`960.40" "cm//sec^2`

B

`984.90" "cm//sec^2`

C

`982.45" "cm//sec^2`

D

`977.55" "cm//sec^2`

Text Solution

Verified by Experts

The correct Answer is:
A
`g.=g/((1+h/R)^2)=980/((1+64/6400)^2)=960.70 cm//s^2`
`~~960.4cm//s^2` approx.
