Given:

The magnetic field applied in a cyclotron is of magnitude 0.7pie T.

To find:

Frequency of elctric field that should be applied between the dees in order to accelerate proton.

Calculation:

Time period in a cyclotron (\tau)

 \therefore \:  \tau =  \dfrac{2\pi r}{v}

 =  >  \:  \tau =  \dfrac{2\pi ( \frac{mv}{Bq}) }{v}

 =  >  \:  \tau =  \dfrac{2\pi ( \frac{m \cancel{v}}{Bq}) }{ \cancel{v}}

 =  >  \:  \tau =  \dfrac{2\pi m}{Bq}

So, frequency is reciprocal of Time period:

 =  > \:  f  =  \dfrac{1}{ \tau}

 =  > \:  f  =  \dfrac{Bq}{ 2\pi m}

 =  > \:  f  =  \dfrac{0.7\pi }{ 2\pi }  \times  \dfrac{q}{m}

 =  > \:  f  =  \dfrac{0.7}{ 2 }  \times 1.04 \times  {10}^{ - 8}

 =  > \:  f  =  0.35  \times 1.04 \times  {10}^{ - 8}

 =  > \:  f  =  0.364 \times  {10}^{ - 8}  \: hz

So, final answer is:

 \boxed{ \sf{\:  f  =  0.364 \times  {10}^{ - 8}  \: hz}}
