Question

2 objects of mass 6 kg and 9 kg are separeted by 12 cm distance . calculate the gravitational force of attraction between them .

pl give ifs ans ​

Answer 1

Answer:

Two objects of mass 6 kg and 9 kg are separated by a 12 cm distance. The gravitational force of attraction between them is $2.47*10^{-7} N$

Explanation:

The gravitational force  is a universal force between any two objects, the force is directly proportional to their masses and inversely proportional to the square of the distance between them

it can be expressed as $F=G\frac{m_{1} m_{2} }{r^{2} }$

where $G=6.610^{-11}Nkg^{2}/m^{2}$(the gravitational constant)

As per the question, we have

the masses of the objects are $m_{1} =6kg$ and $m_{2} =9kg$

the distance between the masses is $r=12cm=0.12m$

substitute the given values to get the force of attraction between them

$F=\frac{6.6*10^{-11}*6*9 }{0.12^{2} } =2.47*10^{-7}N$
