The capacitance, in force-current analogy, is analogous to

The correct answer is C. displacement.

In the force-current analogy, the following analogies can be drawn:

• Force : Current
• Charge : Voltage
• Resistance : Friction
• Capacitance : Displacement

In this analogy, capacitance is analogous to displacement because it is a measure of how much charge can be stored in a capacitor. Just as displacement is a measure of how far an object has moved, capacitance is a measure of how much charge has been stored in a capacitor.

The other options are not correct because:

• Momentum is a measure of the mass and velocity of an object. It is not a measure of how much charge has been stored in a capacitor.
• Velocity is a measure of how fast an object is moving. It is not a measure of how much charge has been stored in a capacitor.
• Mass is a measure of how much matter is in an object. It is not a measure of how much charge has been stored in a capacitor.
