Answer 2

Given:

Mass of each of the two massive particles = 5 mg = 5×10⁻⁶ kg

Gravitational force experienced by the particles = 6.66 dyne = 6.66×10⁻⁵ N

To find:

The separation distance between the two particles.

Solution:

We know that the formula for gravitational force between two particles is:

F = GM1M2/ r²

On re-arranging:

r=√(GM1M2/ F)

On substituting the given values:

r = √(6.67×10⁻¹¹×(5×10⁻⁶)²/ 6.66×10⁻⁵)

r = 5×10⁻⁹ m

Thus the distance of separation between the two particles will be 5×10⁻⁹ m.
