To determine whether we can shield a body from gravitational influence by placing it inside a hollow sphere or through other means, we need to analyze the nature of gravitational forces and compare them to electric forces. ### Step-by-Step Solution: 1. **Understanding Electric Shielding**: - When a charge is placed inside a hollow conductor, the electric field inside the conductor becomes zero due to the redistribution of charges on the surface of the conductor. This phenomenon is known as electrostatic shielding. 2. **Gravitational Force Characteristics**: ...
