A few of the positive particles aimed at a gold foil seemed to bounce back off of the thin metallic foil. so, the correct answer is option A.
<h3>What is the Rutherford experiment?</h3>
Rutherford performed an experiment in which alpha particles are bombarded on the gold foil.
Some of the particles bounced back which indicates that there are heavy particles present in the center of an atom.
Most alpha particles pass through the atom which indicates that there is a lot of empty space in an atom.

Explanation:
Newton’s Second Law of Motion
Newton’s Second Law of Motion states that ‘when an object is acted on by an outside force, the mass of the object equals the strength of the force times the resulting acceleration’.
This can be demonstrated dropping a rock or and tissue at the same time from a ladder. They fall at an equal rate—their acceleration is constant due to the force of gravity acting on them.
The rock's impact will be a much greater force when it hits the ground, because of its greater mass. If you drop the two objects into a dish of water, you can see how different the force of impact for each object was, based on the splash made in the water by each one.
