Acceleration due to GravityHardQuestion 6222

Question

A tunnel through Earth's diameter — period of oscillation of body in tunnel:
  1. A
    Same as satellite period
  2. B
    √(R/g) s
  3. C
    2π√(R/g) s
    Correct
  4. D
    Depends on amplitude

Correct answer

2π√(R/g) s

Explanation

Body in tunnel undergoes SHM with T = 2π√(R/g) ≈ 84 min = 2π√(R/g).
