If the mass of two objects are 10kg and 5 kg and the distance between them is 10 find the force of attraction between them.
Answers
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.
If the mass of two objects are 10kg and 5 kg and the distance between them is 10 find the force of attraction between them...
_______________
✒Given : -
- Mass of 1st Object =10kg
- Mass of 2nd Object =5kg
- Total Distance = ?
✒To Find : -
- Force of attraction = ?
✒By Using Newton's Law : -
➴Here : -
- G = Gravitational Constant .
- G = 6.67 × 10-¹¹ m³ kg-¹ s-² ..
✒On Substituting Values : -
✒Now ,
✒By keeping value of G as constant : -
✒Therefore , Force of attraction between then is G/2 N or 3.335 × 10-¹¹ ..
