Physics · JEE | GRAVITATION
हिन्दीGiven below are two statements: Statement I: The total mechanical energy of an orbiting satellite is negative for any bound system. Statement II: Gravitational shielding can be achieved by placing a body inside a massive hollow spherical shell.
View Answer & Solution
Correct answer · Option C
Statement I is correct but Statement II is incorrect.
Explanation
Total energy of a bound satellite is negative, which is correct. However, unlike electrostatics, gravitational shielding is impossible because a shell does not shield bodies outside from exerting gravitational forces.
