The potential energy of a \(1\) \(kg\) particle free to move along the \(x\)-axis is given by \(V\left( x \right) = \left( {{{{x^4}} \over 4} - {{{x^2}} \over 2}} \right)J\).

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

A
\({3 \over {\sqrt 2 }}\)
B
\({\sqrt 2 }\)
C
\({1 \over {\sqrt 2 }}\)
