Question

how far away from the earth does acceleration due to gravity become 1% of its value at the earth surface? assume that the earth surface is a sphere of Radius= 6.4×10 to the power 6

Answer 1

$theta \div 360 \times 2\pi \: r$
$360 \div 360 \times 2 \times 22 \div 7 \times 6.4 \times 10 \ \: to \: the power \: 6$
