An ionization chamber with parallel conducting plates as anode and cathode has 5 × 107 electrons and the same number of singly charged positive ions per cm3. The electrons are moving towards the anode with velocity 0.4 m/s. The current density from anode to cathode is 4 mA/m2. The velocity of positive ions moving towards cathode is
(a) 0.4 m/s
(b) 1.6 m/s
(c) Zero
(d) 0.1 m/s
