The potential energy of a body is given by, \(U = A – Bx^2\) (where x is the displacement). The magnitude of force acting on the particle is :
Answer & explanation
Correct answer: option 1
Force is given by : \(F = \frac{dU}{dx}\)
\(F = \frac{d}{dx}(A - Bx^2)\)
\(F = -2Bx\)
\(\Rightarrow F \propto x\)
