<u>Answer</u>:
(C) The positive charge of the alpha particles and the negative charge of the electrons are the properties Rutherford used in his experiment
<u>Explanation</u>:
In his scattering experiment, scientist Ernest Rutherford used the property of positively charged alpha particles and negatively charge electrons. He performed this experiment by passing some of the alpha particles through a gold foil. The result was that the some alpha particles scattered while some passed through the gold foil without collision.
He concluded that the alpha particles are centrally positively charged and needed a large amount repelling force. This experiment of Rutherford is also known as Rutherford model of atom. This experiment helped him in doing so many other discoveries.
They do have the same mass. However, “Heavy” implies we are concerned with how much force it takes to lift the object. In this case, we will find that the force needed to lift a kilo of feathers in air is slightly less than that needed to lift the kilo of lead.
