Question

Potential energy v/s displacement curve for the one-dimensional conservative field is shown. The force at A and B are respectively.

• A. Positive, Posltive
• B. Positive, Negative
• C. Negative, Positive
• D. Negative. Negaiive

Answer 1

The correct option is B Positive, Negative

Here in the figure at point A potential energy is decreasing, So kinetic energy is increasing. So, Force at A is +Ve.

And At Point B potential energy is increasing, So kinetic energy is decreasing. So, Force at A will be -Ve.

To move the object more force is required and making object move less force is required.

Answer (B) Positive, Negative
