Q. In Thomson spectrograph experiment, four positive ions $P,Q,R$ and $S$ are situated on $Y$-$X$ curve a shown in the figure
A) The specific charge of $R$ and $S$ are same
B) The masses of $P$ and $S$ are same
C) The specific charges of $Q$ and $R$ are same
D) The velocities of $R$ and $S$ are same
Explanation
(a) All the positive ions of same specific charge moving with different velocity lie on the same parabola
