CONCEPT:
- Potential Energy: The energy stored in the body or system by virtue of its configuration or its position is called potential energy.
- Force: Force is the external agency that tends to change the state of motion of a body.
- It has both magnitude and direction.
EXPLANATION:
- The potential energy is equal to negative work done in shifting an object from some reference point to a given position for conservative force.
In mathematical form, it is given as,
\({\mathrm{d} U(x)}=-F(x){\mathrm{d} x}\)
\(\therefore\) \(F(x)=\dfrac{-dU(x)}{dx}\)
where F is the force in newton and dU/dx is change in potential energy per unit length.
The answer is option 1).
