Question

Select One Option Correct from the following :A particle, which is constrained to move along x-axis, is subjected to a force in the same direction which varies with the distance x of the particle from the origin as $F(x) = -kx +ax^3$ Here, k and a are positive constants. Here, k and a are positive constants.For $x \geq 0$ the functional form of the potential energy U (x) of the particle is (Refer given image for the options)
