1. The problem statement, all variables and given/known data A point particle of mass m carrying an electric charge q is attatched to a spring of stiffness constant k.A constant electric field E aong the direction of spring is switched on for a time interval T (T<<Sqrt(m/k)). Neglecting radiation loss,Find the amplitude of oscillation after the field is switched off. 2. Relevant equations 3. The attempt at a solution No idea where to start.Please give me a hint. Thank you very much.
