Answer:

q_end = q / 4  

Explanation:

Since the balls are in insulating barrels, it has no charge exchange with the earth, so it maintains its initial charge.

 

When the ball a touches the ball b and since the two are metallic the charge is distributed over the entire surface, by separating the two spheres that are of the same radius, the load was distributed between the two,

           

              q_end = q₀ / 2

              q_end = (q / 2) / 2

              q_end = q / 4

This is the charge on each ball.

If we keep touching the balls nothing else happens because the charges are already equal in both.

Who did not have experimental evidence to support his theory of the atom? Dalton Thomson Rutherford Democritus
Aloiza [94]

Democritus was the one who did not have experimental evidence to support his theory of the atom.

Answer: Option 4

<u>Explanation: </u>

The discovery of atoms were first stated by Democritus but due to the absence of any experimental proof, his statement was not noted as significant at that time.

After this, Dalton made the specific assumptions formulating some postulates for the atomic theory with proof. Then the cathode rays tube experiments performed by Thomson lead to the formation of plum pudding models of atom.

This is followed by Rutherford’s gold foil experiment discovering the presence of nucleus inside the atoms. So, Democritus first stated but due to absence of experimental evidences, his theory of atoms were not supported at that time.
