when 
= 0 it means no there is no external torque so hence no workdone
due to torque.
so work done will be Zero

Find the law of motion of a particle mass m and zero energy in
one dimension in the field U(x) = -Ax^(4) where A is a positive
constant. Given the inital position x0, compute how much time does
it take for the particle to escape to infinity if the vector of
initial velocity of the particle is pointing away from the origin
x=0. Describe the motion when the vector of inital velocity of the
particle is pointing toward x=0.
