Question

ike is conducting a scientific experiment involving clear adhesive tape. he completes each of the following steps: 1. he removes two strips of tape from the roll. 2. he presses each strip of tape, sticky - side down, on a plastic surface. 3. he quickly removes each strip of tape from the plastic surface. ikes teacher tells him that this process has caused each strip of tape to gain a negative electric charge. what could ike demonstrate that the negative charge of each strip has generated an electric field? a. see if the strips will stick together when the sticky sides are pressed together b. see if the strips repel each other when brought close together c. see if one of the strips is longer or more massive than the other d. see if the strips respond to the force of gravity when dropped from a height

Explanation:

Charges of the same sign repel each other. Since both tape - strips have a negative charge, if they repel when brought close together, it indicates the presence of an electric field. Option A shows adhesion which is not related to electric field due to charge. Option C about length and mass has no connection to electric charge and field. Option D is about gravity, not electric field.

Answer:

B. see if the strips repel each other when brought close together
