Question

find the force between the masses 5g
and 15g separated by distance 3m​

Answer 1

Given:

Mass of first object (m1) = 5g

Mass of second object (m2) = 15g

Distance between the objects = 3m

To find:

The gravitational force between the 2 objects.

Solution:

• The gravitational force can be calculated by the formula-

        F = G(m1 x m2) /r²

• Substituting the values, we get,

        F = 6.67 x 10⁻¹¹ (0.005 x 0.015) / (3)²

           = 55.58 x 10⁻¹⁷ N

• Thus the force between those objects is 55.58 x 10⁻¹⁷ N.
