Use the table of electric force between objects in two different interactions to answer the question. Interaction Charge on Object 1 (C) Charge on Object 2 (C) Amount of Force
A +1 –2 weak
B +1 +2 strong
Which conclusion about the interactions is correct?

(1 point)

Repulsive forces are stronger than attractive forces.

The objects in interaction A are farther apart than in interaction B.

The objects in interaction A are smaller than in interaction B.

Positive charges are stronger than negative charges.

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?

Uppose we consider the system of the three capacitors as a single "equivalent" capacitor. given the charges of the three individual capacitors calculated in the previous part, find the total charge qtot for this equivalent capacitor. express your answer in terms of v and c.
