11.Dual Nature of Radiation and matter
medium
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
Solution
(a) All the positive ions of same specific charge moving with different velocity lie on the same parabola.
