A charged particle of mass m and charge q is moved fromx=0 by an electric field E→=(E0−αx)i∧ where α is the positive constant and x is the displacement of the particle in time t along x-axis. Find the distance moved by a particle when it is again brought to rest and the acceleration of the particle at that instant. Describe the motion of the particle.
