The product of m1m2 in the formula for gravitational force is always negative, because the product of two positive numbers is negative.

positive, because the product of two positive numbers is positive.

positive, because the product of two negative numbers is positive.

negative, because the product of two negative numbers is negative.

The correct answer is the second option

Explanation:

The formula in question (for gravitational force) is provided below

F = G.m₁.m₂/r²

Where

F = force of gravity

G = gravity constant (6.674 × 10⁻¹¹ m.kg⁻¹.s⁻²)

m₁ and m₂ = are the masses of the objects

r² = distance between the centers of the two objects

From the above, it can be deduced that m₁ and m₂ are masses and hence can only be positive. Positives multiplied together only gives positive, thus the second option is correct.
