In the figure shown, m_(a)=m_(b)=1kg block-A is neutral while block-B carriescharge -1c. Sizes of A and B are negligible. Block-B is released from rest at a distance 1.8m from A. Initially spring is neither compressed nor stretched. If collision between A and B is perfectly inelastic, then velocity of the combined mass just after collision is
