An ion carrying a charge 6*4 xx 10^(-19)...

An ion carrying a charge `6*4 xx 10^(-19)C` is revolving in circular path in a magnetic field of intensity ` 4 xx 10^(-4)` Tesla. Calculate the frequency of revolution if the mass of ion is `2*8 xx 10^(-26)` kg.

Text Solution

Verified by Experts

`q = 6*4 xx 10^(-19)C`
`B = 4 xx 10^(-4)` T
Frequency = v = ?
`m = 2*8 xx 10^(-26)` kg
`v = (Bq)/(2pim)`
` = (4 xx 10^(-4) xx 64 xx 10^(-19))/(2 xx 3*14 xx 2.8 xx 10^(-26))`
