A particle of mass \( m \) and charge \( q \) is moving in a region where uniform, constant electric and magnetic field \( E \) and \( B \) are present. \( E \) and \( B \) are parallel to each other. At time \( t=0 \), the velocity \( v_{0} \) of the particle is perpendicular to \( E \). Find the velocity \( v \) of the particle at time \( t \). You must express your answer in terms of \( t, q, m \), the vectors \( v_{0}, E, B \) and their magnitudes \( v_{0}, E \) and \( B \)
