Surface of Earth is considered at .........

Surface of Earth is considered at ...... gravitational potential (in practice).

A

infinite

B

negative

C

positive

D

zero

Text Solution

Verified by Experts

In practice absolute value of gravitational potential is not important, but change in potential Is important. Hence, any value of gravitational potential can be considered on the surface of Earth. But in practice, in order to have ease in the calculations, we prefer to select the value of gravitational potential on the surface of Earth to be zero.
