COMEDK · Physics · 9. Gravitation
The height vertically above the earth's surface at which the acceleration due to gravity becomes \(1 \%\) of its value at the surface is
- A 20R
- B 10R
- C 9R
- D 8R
Answer & Solution
Correct Answer
(C) 9R
Step-by-step Solution
Detailed explanation
The acceleration due to gravity at a height \(h\) above the surface of the earth is given by the formula \(g_h = g \left( \dfrac{R}{R+h} \right)^2\), where \(g\) is the acceleration due to gravity at the surface and \(R\) is the radius of the earth. Given that…
