To compare the weight of a body when it is at (a) 80 km above the Earth's surface and (b) 80 km below the Earth's surface, we will use the formulas for gravitational acceleration at different heights and depths. ### Step 1: Calculate the weight of the body at 80 km above the Earth's surface. 1. **Given data:** - Radius of the Earth (R) = 6400 km - Height (h) = 80 km - Acceleration due to gravity at the surface (g) = 9.8 m/s² ...
