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 1

The answer is D.

I just took the test and got it right

Answer 2

The answer is C. Frictional charging is primarily involved. In the scenario, the bouquet of flowers represents a charged object that causes an electron (or the flower) to transfer from one object to another. Due to the bouquet of flowers, the other flower repelled and moved towards the object with a lesser charge. As a result, the box becomes neutral or has no charge at all.
