Which of the following fields is dependent on the path?
Correct answer: C. Non-conservative field
- A. Gravitational field
- B. Conservative field
- C. Non-conservative field
- D. None of these
Explanation
A conservative force is a force that does not depend on the path taken. The work done by a conservative force is independent of the path taken.A non-conservative force is a force that depends on the path taken. The work done by a non-conservative force is dependent on the path taken.Example:Gravitational force is a conservative force. The work done by gravity in moving an object from one point to another is independent of the path taken.Frictional force is a non-conservative force. The work done by friction in moving an object from one point to another is dependent on the path taken.

About Work and Energy
Work transfers energy when a force causes displacement, while kinetic energy, gravitational potential energy and power describe motion, position and the rate of energy transfer. The work-energy theorem links net work with change in kinetic energy, and efficiency accounts for energy losses rather than treating them as energy destruction.
