Question

two spherical object having masses of 8000 kg and 1500 kg.their senter are seprated by distance of 1.5 m . find the gravitatinal attraction btween them

Answer 1

Answer:

Two objects are separated by a distance of 1.5m, having masses of 8000 kg and 1500 kg,  the gravitational attraction between them  is $F=3.52*10^{-4}N$

Explanation:

• The gravitational force is the interaction between two objects with mass

• If two bodies with masses $m_{1}, m_{2}$ are separated by a distance $r$, the force between them is

        $F=G\frac{m_{1} m_{2} }{r^{2} }$

        where $G=6.6*10^{-11} Nm^{2} kg^{-2}$

From the question, we have

masses of the spherical objects $m_{1} =8000kg$  $m_{2} =1500kg$

distance between their centers $r=1.5m$

⇒

the gravitational force,

$F=\frac{6.6*10^{-11}*8000*1500 }{1.5^{2} }$

$F=3.52*10^{-4}N$
