Answer 1

Answer:

answer is 9Newton for this question

Answer 2

Solution

now....

$\frac{g(h)}{g(o)} = \frac{r {}^{2} }{(r + h) {}^{2} } \\ = > \frac{g(h)}{g(o)} = \frac{r {}^{2} }{(r + 2r) {}^{2} } = \frac{1}{9} \\ = > g(o) = g(h).9$

now....

mg(o)=72

=>mg(h)×9=72

=>mg(h)=8 N

at height of h=2R it's weight would be= 8N
