AI Generated Solution

To compare the weights of a body when it is (i) 200 km above the surface of the Earth and (ii) 200 km below the surface of the Earth, we can use the formulas for gravitational acceleration in both scenarios. ### Step 1: Define the Variables - Let \( R \) be the radius of the Earth, which is \( 6400 \, \text{km} \). - Let \( h \) be the height above the Earth's surface, which is \( 200 \, \text{km} \). - Let \( d \) be the depth below the Earth's surface, which is also \( 200 \, \text{km} \). ### Step 2: Calculate the Gravitational Acceleration Above the Surface ...
