whats is the formula for Acceleration due to gravity (gd)at a depth 'd' from earth surface ?

  1. gd = g(1- d )/R

  2. gd = G (M1 M2 )/2

  3. gd = g(2+ d)/9

  4. Gd = g(1-d)/ R

A Correct answer
Explanation

The formula for acceleration due to gravity at depth 'd' from Earth's surface is gd = g(1 - d/R), where g is surface gravity and R is Earth's radius. This shows that gravity decreases linearly as we go deeper inside Earth, becoming zero at the center.
