An ionization chamber with parallel conducting plates as anode and cathode has

An ionization chamber with parallel conducting plates as anode and cathode has 5 x 10 electrons and the same number of singly charged positive ions per cm. The electrons are moving towards the anode with velocity 0.4 m/s. The current density from anode to cathode is 4A/m. The velocity of positive ions moving towards cathode is (a) 0.4 m/s (c) zero (b) 1.6 m/s (d) 0.1 m/s
