MHT CET · Physics · Gravitation
The depth at which the value of acceleration due to gravity becomes
\(\left(\frac{1}{n}\right)\) times the value at the surface of the earth is
( \(R=\) radius of the earth)
- A \(\frac{R(n-1)}{n}\)
- B \(\frac{R(n+1)}{n}\)
- C \(\frac{\mathrm{Rn}}{(\mathrm{n}-1)}\)
- D \(\frac{\mathrm{R}}{\mathrm{n}}\)
Answer & Solution
Correct Answer
(A) \(\frac{R(n-1)}{n}\)
Step-by-step Solution
Detailed explanation
\(g_d = g \left(1 - \frac{d}{R}\right)\) \(\frac{g}{n} = g \left(1 - \frac{d}{R}\right)\)
