Q. The specific charge for positive rays is much less than that for cathode rays. This is because
A) Masses of positive rays are much larger
B) Charge on positive ray is less
C) Positive rays are positively charged
D) Experimental method is wrong
Explanation
(a) Specific charge=charge/mass. The positive rays are stream of positive ions. The mass of positive ion is much more than that of electrons, hence specific charge of positive ions is less
