A block of mass m having a charge q is placed on a smooth horizontal table and is connected to the wall through an unstretched ideal spring of force constant k A horizontal uniform electric field E as shown in figure is suddenly switched on Assume that charge is only confined to the block and induced charges are not produced elsewhere The motion of the block is A simple harmonic with an amplitude of qE k B simple harmonic with an angular frequency of 2k m C not simple harmonic but has an amplitude of qE k D not simple harmonic but has an amplitude of 2qE k THE
