Question

Marta, Cato, and Juan plan a skit to illustrate one of the methods of charging. Marta and Cato are walking together. Each has one flower and one box of candy. Juan offers Cato a huge bouquet of flowers, but Cato can’t take it because his hands are full. Cato hands his flower to Marta and then turns to Juan to take the bouquet. Marta walks away in one direction with two flowers and one box of candy. Juan keeps the bouquet and walks away in the other direction. Cato looks sad standing alone with only a box of candy.

How does the skit model a method of charging?

A) It models induction because an electron (a flower) transfers from Cato to Marta through direct contact.

B) It models friction because an electron (a flower) transfers from Cato to Marta through direct contact.

C)It models friction because the offer of flowers represents a charged object that causes an electron (a flower) to transfer from one object to another.

D) It models induction because the offer of flowers represents a charged object that causes an electron (a flower) to transfer from one object to another.

Answer 2

Option D.

Step-by-step explanation:

Methods of charging:

1. By friction: when two materials of different electro-negativities rub against each, electrons transfer from one material to another.

2. By induction: When a charged body is brought near an uncharged body, the later gets polarized.

3. By conduction: when electrons from one body to another uncharged while contact, it is known as charging by conduction.

Here, a flower is analogous to an electron. A box of candy is positive charge. A bouquet of flowers is like a charged body which is brought near an uncharged body. It induces charge on ti it by causing it to transfer electron to another.

Thus, option D is correct.
