Question

3. When a magnetic sector instrument was operated with an accelerating voltage of 4.50*103 V, a field of 0.251 T was required to focus the CH4 on the detector. a) What range of field strengths would be required to scan the mass range between 12.5 and 2.50*102 , for singly charged ion, if the accelerating voltage is held constant

Answer 1

The answer is "
`4,500 - 225 \ V`".

Step-by-step explanation:

Using formula for calculating the Voltage:

`M_1=12.5\\\\M_2=250\\\\V_1=4,500 \\\\\bold{\text{Formula: }}\\\\\to \bold{(m_1)/(m_2)=(V_2)/(V_1)}\\\\\to (12.5)/(250)=(V_2)/(4,500)\\\\\to 0.05=(v_2)/(4,500)\\\\\to 0.05* 4,500= V_2\\\\\to V_2=225\\\\`

Hence the range of accelerating in voltage is
`4,500 - 225 \ V`
