When value of q is kept constant, the value of m/e is proportional to which of the following when ‘m’ is the mass number, ‘e’ is the electric charge, ‘u’ is the DC potential, ‘v’ is the peak amplitude and ‘f’ is the frequency?
A. u/v ratio
B. u
C. v
D. f
Answer:C
When value of q is kept constant, the value of m/e is proportional to which of the following when ‘m’ is the mass number, ‘e’ is the electric charge, ‘u’ is the DC potential, ‘v’ is the peak amplitude and ‘f’ is the frequency?
A. u/v ratio B. u C. v D. f
Explanation: When value of q is kept constant, the value of m/e is proportional to ‘v’. By variation of rf amplitude the m/e ratio varies.
