Which type of ionic species are allowed to pass through the slit and reach the collecting plate?
A. Negative ions of all masses
B. Positive ions of the specific mass
C. Negative ions of the specific mass
D. Positive ions of all masses
Answer:B
Which type of ionic species are allowed to pass through the slit and reach the collecting plate?
A. Negative ions of all masses B. Positive ions of the specific mass C. Negative ions of the specific mass D. Positive ions of all masses
Explanation: Positive ions of specific mass pass through the slit and reach the collecting plate. The ion currents are measured using sensitive electrometer tube. The ions reaching the collecting plate are measured.
