Abstract: We analyze the motion of charged particles in rotating pulsar magnetosphere using the equation of motion, which was proposed earlier. We consider the projected magnetic field lines onto a 2D plane perpendicular to the rotation axis, and derive the particle trajectory valid over a radial distance of about 10% of the light cylinder radius. The motive behind considering this model is to elucidate some of the effects of rotation on pulsar profiles. For example, the asymmetry in the observed pulse shapes can be explained by considering the aberration-retardation effects. The single sense circular polarization that has been observed in many pulsars, might be due to the relative orientation of sight line with respect to the plane of particle trajectory.
