A cyclotron is operating at a frequency of 12xx10^(6)Hz. Mass of deuteron is 3.3xx10^(-27) kg and its charge is 1.6xx10^(-19) C. To accelerate the deuterons, the magnetic induction of the field required is :

Answer»

16 T
1.6 T
0.16 T
0.016T

Solution :Here `B q v=(MV^(2))/(r)`
`:. (v)/(r)=(Bq)/(m)`
`:. omega= (Bq)/(m)`
or `2pi n=(Bq)/(m)`
`B=(2pi nm)/(q)`
Here `n=12xx10^(6)Hz`
`m=3*3xx10^(-27)kg`
`q=1*6xx10^(-10)C`
`:.B=(2XX3*14xx12xx10^(6)xx3*3xx10^(-27))/(1*6xx10^(-19))T`
`=1*6T`
