Question

Find the force of attrraction between two masses of 2kg and 4kg having a distance of 2m
(GIVEN G=6.67×10-11NM 2kg-2)

Answer 1

We know that,

• The force of attraction between any two objects is gravitational force and the formula for this force is;

= $\huge{\boxed{\sf{F=G\dfrac{F_{1}.F_{2}}{{r}^{2}}}}}$

And from the question we have,

• Mass of objects = 2kg & 4kg
• Distance = 2 m
• Gravitational constant = 6.67 × 10-¹¹

Just put these all values in the above formula;

• ${\sf{F=G\dfrac{F_{1}.F_{2}}{{r}^{2}}}}$
• F = ${\sf{\dfrac{ 6.67 × {10}^{-11} ×2 × 4}{{2}^{2}}}}$
• F = ${\sf{\dfrac{ 6.67 × {10}^{-11} ×2 × 4}{4}}}$
• F = ${\sf{ 13.34 × {10}^{-11} }}$

Thus, the force acting between these two objects is 13.34 × 10-¹¹ N kg² m-², which as you can see is very very very small.
