Four identical point charges are fixed at the four corners of a square of a side length l. Another charged particle of mass m and charge +q is projected towards centre of square from a large, distance along the line perpendicular to plane of square. The minimum value of initial velocity `V_(0)` in m/s required to cross the square is? `(m = 1gm.l=4sqrt(2)m,Q=1muc,q=0.5muc)`
