Hint: To solve this problem we can use Newton’s law of universal gravitation which states that each particle in the universe experiences a hidden force which is known as gravitational force. The gravitational law states that the magnitude of this force is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centres. The force is a universal attractive force and it is also the weakest force of nature. The gravitational force is an extremely long range force. The equation for the gravitational force is represented by this equation,
$F = G\dfrac{{{m_1}{m_2}}}{{{r^2}}}$, where $F$ is the gravitational force between particles, ${m_1}$ and ${m_2}$ are the masses of the particles, $r$ is the distance between the centres of their masses.
Complete step by step answer:
If we allow the gravitational law on the dust particles , we have found that the dust particles also have mass so it also feels gravitational force. It remains in the air current because it is carried by air due to its lightweight. The gravitational forces act along the line joining the centre of mass of particles. It does not depend on the medium between the two bodies so this force acts on every system and body on the earth. So the correct answer of the above question is yes and option A is correct the force of the gravity acts on the dust particle.
So, the correct answer is “Option A”.
Note: We know by Newton's law of universal gravitational, all mass experiences a kind of attraction which binds them together. This force influences everything no matter how small it is. We can stand on earth easily only because of the gravitational force. The gravitational force of the earth is acting as a magnet pulling us on the ground.
