An ion carrying a charge `3*2 xx 10^(-19)` C is revolving in circular path in a magnetic field of intensity `2 xx 10^(-4)` Tesla. Calculate the frequency of revolution if the mass of ion is `7*0 xx 10^(-27)` kg .

Explanation

` q = 3*2 xx 10^(-19)` C
`B = 2 xx 10^(-4)` T
Frequency = v = ?
`m = 7*0 xx 10^(-27)` kg
`v = (Bq)/(2pim)`
`v = (2 xx 10^(-4) xx 3*2 xx 10^(-19))/(2 xx 3*14 xx 7*0 xx 10^(-27))` ` = 0*1456 xx 10^(4)`
`v = 1*456 xx 10^(3)` Hz
