method given by BONEY is correct but formula is not correct

it should be B = 4×{ (μ0I) / 4πR } × [sinθ1+ Sinθ2]

the resultant dipole moment is √2M  thus  the resultant magnetic  field is  μ2√2M/4πd3   (ans)

this answer is given by sarika and is correct answer

B = μ0/2 * i/r

and i = e/T

and T = 2πr/v

solve

when charge will move from first dee to second dee it will gain qV and on returning to first dee it will gain qV again so in one revolution it will gain 2qV so in n revolutions it will gain 2qVn

potential diff b/w dees of cyclotron is V , if charge q comes out of it after completing n revolution then gain in KE of charge is 2nqV HOW?
