Question

the force of attraction between two identical masses is 6.673×10 -7 N when they are 1 m apart what are the masses if
​

Answer 1

Answer:

10² kg

Explanation:

Given :

Two object of same masses

Attraction force is  6.673 × 10⁻⁷ N

Distance between them is 1 m .

We have to find their masses .

We know formula for Force :

F = G M m / R²

where G is Gravitation constant and of value 6.673 × 10⁻¹¹ N m² / kg²

Let say mass be m

Putting values in formula we get :

6.673 × 10⁻⁷ = 6.673 × 10⁻¹¹ m  ×  m / 1²

1  × 10⁻⁷ = 10⁻¹¹ m  ×  m

m  ×  m = 10⁴ kg

m = 10² kg .

Hence we get mass is 10² kg of each .
