A particle which is constant to move along the `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)` . Hero `K` and `a` are positive constant . For `x ge 0`, the fanctional from of the patential every `U(x) of the particle is

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. For x ge 0 , the functional form of the potential energy U (x) of the particle is

A particle, which is constrained to move along x-axis, is subjected to a force in the some direction which varies with the distance x of the particle from the origin an F (x) =-kx + ax^(3) . Here, k and a are positive constants. For x(ge0, the functional form of the potential energy (u) U of the U (x) the particle is. (a) , (b) , (c) , (d) .
