Question

A particle of mass 'm' moves in one-dimensional potential energy u(x) = ax2 + bx4, where 'a' and 'b' are positive constants. Angular frequency of small oscillations about the minima of the potential energy is equal to

Answer 1

A particle of effective mass m is acted on by a potential energy given by ... 0 (! ax2 + bx4 ) ... a , and b are positive constants. ... frequency of small oscillation.
