Given

☞ Mass of one object = 10 kg

☞ Mass of 2nd object = 5 kg

☞ Distance b/w them = 10 m

To find

Force of attraction b/w them.

Solution

From the data we have ;

☞ Mass of 1st object (m₁) = 10 kg

☞ Mass of 2nd object (m₂) = 5 kg

☞ Distance (d) = 10 m

Now we will use Newton's law :-

F = (Gm₁m₂)/d²

Where,

  • G is Gravitational constant
  • G = 6.67 × 10-¹¹ m³ kg-¹ s-²

Now putting values we get,

⟼ F = (6.67 × 10-¹¹ × 10 × 5)/10²

⟼ F = (6.67 × 10-¹¹ × 50)/100

⟼ F = (6.67 × 10-¹¹)/2

F = 3.335 × 10-¹¹ N

But if you keep value of G as constant,

⟼ F = G(10 × 5)/10²

⟼ F = G(50)/100

F = G/2 N

Force of attraction between them = 3.335 × 10-¹¹ N or, G/2 N.

Given : -

  • Mass of 1st Object \sf{({m}_{1})}=10kg
  • Mass of 2nd Object \sf{({m}_{2})}=5kg
  • Total Distance = ?

To Find : -

  • Force of attraction = ?

By Using Newton's Law : -

\leadsto\sf{F=\dfrac{G({m}_{1})({m}_{2})}{{d}^{2}}}

Here : -

  • G = Gravitational Constant .
  • G = 6.67 × 10-¹¹ m³ kg-¹ s-² ..

On Substituting Values : -

\dashrightarrow\sf{F=\dfrac{(6.67\times{{10}^{-11}\times{10}\times{5})}}{{10}^{2}}}

\dashrightarrow\sf{F=\dfrac{(6.67\times{{10}^{-11}\times{\cancel{50})}}}{\cancel{100}}}

\dashrightarrow\sf{F=\dfrac{(6.67\times{{10}^{-11})}}{2}}

\dashrightarrow\sf{F=3.335\times{{10}^{-11}}}N

Now ,

By keeping value of G as constant : -

\dashrightarrow\sf{F=\dfrac{G(10\times{5)}}{{10}^{2}}}

\dashrightarrow\sf{F=\dfrac{G(50)}{100}}

\leadsto\sf{F=\dfrac{G}{2}}N

✒Therefore , Force of attraction between then is G/2 N or 3.335 × 10-¹¹ ..
