Question

Choose the correct alternative:

Acceleration due to gravity increases/decreases with increasing depth. (assume the earth to be a sphere of uniform density).

Advertisements

Solution

Decreases

Acceleration due to gravity at depth d is given by the relation:

`g_d = (1-d/R_e)g`

It is clear from the given relation that acceleration due to gravity decreases with an increase in depth.
