Question

. The gravitational force between two identical lead spheres kept at 1m apart is 0.00667 N . Find their masses.​

Answer 1

Explanation:

F = G m1 m2 /r^2

where G is universal gravitational constant=6.67×10^-11

m are masses

and r is distance between them

Answer 2

Answer:

Given : F=0.0667 mg wt =0.066×10 power -6 ×10 N , r=1 m

Using the expression: F= Gmm/r²

Plugging in the values, we get:

⇒F= (6.67× 10-¹¹) (m²) /1²

⇒0.0667×10 power -5 = (6.67× 10-¹¹) (m²) /1²

⇒6.67×10 power -7= (6.67× 10-¹¹) (m²) /1²

⇒m²= 6.67×10 power -7/ 6.67× 10-¹¹ = 10⁴kg

⇒m=100 kg
