Answer:

Some of the heavy particles bounced off the foil, because there is a dense, positive area in the atom.

Explanation:

In Rutherford experiment following is the observations made by the Rutherford

1). Major part of the alpha particles will go out undeviated which shows that major portion of the atoms vacant or empty space

2). Few part of the alpha particle moves out with deviation in path which shows that electrons moves in different shells and when alpha particles pass through a given electron then it will show the deviation in path

3). very few alpha particles will get deviated by 180 degree and returns to original path which shows the presence of nucleus. So nucleus is made up of positive charge which is concentrated at very small space

so here correct answer would be

Some of the heavy particles bounced off the foil, because there is a dense, positive area in the atom.

Complete Question

A parallel-plate capacitor, with air dielectric, is charged by a battery, after which the battery is disconnected. A slab of glass dielectric is then slowly inserted between the plates. As it is being inserted,

A :

a force repels the glass out of the capacitor.

B :

a force attracts the glass into the capacitor.

C :

no force acts on the glass.

D :

a net charge appears on the glass.

E :

the glass makes the plates repel each other.

Answer:

The correct option is B

Explanation:

Generally when the glass dielectric is slowly inserted between the plated,

The positive plate of the capacitor will induce a negative charge on the glass while the negative plate of the capacitor will induce a positive charge on glass which a electric field that posses an electric force that will attract the glass
