Physics · JEE | GRAVITATION

हिन्दी

Given 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.

  1. A
    Both Statement I and Statement II are correct.
  2. B
    Both Statement I and Statement II are incorrect.
  3. C
    Statement I is correct but Statement II is incorrect.
  4. D

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.
