The height in terms of radius of the earth (R), at which the acceleration due to gravity becomes g/9, where g is acceleration due to gravity on earth's surface, is ______. (a) √(3)R (b) 2√(2)R (c) 2R (d) 4/9R

Answer: (c). (R/R+h)² = 1/9 R + h = 3R ⇒ h = 2R So the answer is (c) 2R.

Acceleration Due to Gravity

The height in terms of radius of the earth $(R)$ , at which the acceleration due to gravity becomes $\frac{g}{9}$ , where $g$ is acceleration due to gravity on earth's surface, is

______.

Show answer and solution

Answer: (c)

$\left(\frac{R}{R+h}\right)^2 = \frac{1}{9}$
$R + h = 3R \Rightarrow h = 2R$
So the answer is (c) $2R$ .
