Question

which of the following is a tool used to conduct experiments with electric charges? answer options: select one of four caliper ammeter pith ball incubator

Explanation:

• A caliper is used for measuring dimensions, not electric charge experiments.
• An ammeter measures electric current, not directly for charge experiments.
• A pith ball is used to demonstrate electrostatic phenomena (like attraction/repulsion of electric charges).
• An incubator is for controlling temperature in biological experiments.

Answer:

C. Pith ball
