Particle Motion in Uniform Electric and Magnetic Fields

[Tachyon_Jay]

Homework Statement

A particle of charge q and mass m is projected on a rough horizontal plane (X-Y) from a point (a,0,0) with initial velocity v = V j . In space there exists uniform electric and magnetic field E k and -B k respectively. Acceleration due to gravity is g and friction coefficient between particle and plane is u . The particle moves on a spiral path and finally reaches origin O. The time taken to reach the origin = ?
