Question

Find gravitational force between two object of mass 1kg and 5kg which are kept at a distance of half metre

Answer 1

Answer:

• Gravitational force between the two objects will be 13.4 × 10⁻¹⁰ Newton

Explanation:

given,

• mass of two objects 1 kg and 5 kg , let m₁ = 1 kg and m₂ = 5 kg
• distance between two objects, d = 1/2 m

We need to find,

• Gravitational force between the two objects, F = ?

so,

Using formula

• F = G m₁ m₂ / d²

[ where F is the gravitational force between two objects of masses m₁ and m₂  ; d is the distance between the two objects ; G is the universal gravitational constant ]

(taking value of G as 6.7 × 10⁻¹¹ N kg⁻² m² )

→ F = (6.7 × 10⁻¹¹) ( 1 ) ( 5 ) / ( 1/2 )²

→ F = (6.7 × 5 × 10⁻¹¹ / ( 1 / 4 )

→ F = 6.7 × 5 × 4 × 10⁻¹¹

→ F = 134 × 10⁻¹¹

→ F = 13.4 × 10⁻¹⁰  Newton

Therefore,

• Gravitational force between the two objects will be 13.4 × 10⁻¹⁰ Newton .
