At what height the acceleration due to gravity decreasing by 51 % of its value on the surface of th earth ?

Explanation

To find the height at which the acceleration due to gravity decreases by 51% of its value on the surface of the Earth, we can follow these steps:

### Step 1: Understand the Problem
We need to determine the height \( h \) where the acceleration due to gravity \( g_h \) is 49% of the surface gravity \( g \) (since a decrease of 51% means we have 49% remaining).

### Step 2: Write the Equation for Gravity at Height
The formula for the acceleration due to gravity at a height \( h \) above the Earth's surface is given by:
\[
