At a distance $320 km$ above the surface of the earth, the value of acceleration due to gravity will be lower than its value on the surface of the earth by nearly (radius of earth = $6400 km$ )

Options:

Answer:

Solution:

$\frac{g'}{g} = 1 - \frac{2 h}{R} = 1 - \frac{2 \times 320}{6400} = 1 - \frac{1}{10} = \frac{9}{10}$

$∴$ % decrease in $g = (\frac{g - g'}{g}) \times 100$

$= \frac{1}{100} \times 100 = 10 %$
