Question

While conducting a lab, a physics student tried to charge different objects. She notices that the first object, caused the electroscope to deflect greatly and the second object did not deflect the electroscope at all. Which of the following can she conclude about the two objects? Select all that apply.

Object 1 is an insulator and object 2 is a conductor.

Object 1 is a conductor and object 2 is an insulator.

Object 1 could be rubber and object 2 could be copper.

Object 1 could be copper and object 2 could be rubber.

Object 1 could be used to connect a circuit together.

Object 2 could be used to connect a circuit together.

Answer 1

2,4,5 is your answer

Answer 2

Option 2 Object 1 is a conductor and object 2 is an insulator.

Option 4 Object 1 could be copper and object 2 could be rubber.

Object 5 Object 1 could be used to connect a circuit together.

Step-by-step explanation:

An electroscope is a device that is used to identify and measure that whether the given object carries or bear a current or not.

First object deflects the electroscope which means it carries the current and only a conductor can carry a current. Thus, the first object must be a conductor.

On the other hand second object do not deflects the electroscope which means it does not carries the current and hence it is an insulator.

Copper is a conducting material while rubber is a non conducting material. Also a conducting material is used to connect a circuit.

Thus, option 2, 4, 5 are correct.
