If a particle has total energy greater than or equal to potential energy of the force field, it wouldn't remain confined, it would escape out. But as per the question, they said it is confined, that is, E of particle should be less than U(X)🤔

sirrr q clearly said partixle is in motion so k.E cant be zero
Therefore A should be the ans

The potential energy of a 1 kg particle free to move along the x-axis is given by

V(x) = ((x ^ 4)/4 - (x ^ 2)/2) * J

The total mechanical energy of the particle is 2J. Then, the maximum speed (in m/s) is
