In a parabola spectrograph, the velocities of four positive ions 
and S are 
and 
respectively
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
In Thomson mass spectrograph. All the charged particle moving with difference velocity but same charge to mass ratio lie on the same parabola. and 
Hence ion whose deflection is less velocity will be more.
For curve 
Hence
