Explanation Given data: Energy of the electrons in the beam ( E beam ) is 10 MeV . The beam current ( I ) is 0.30 mA . The energy required to deposit in a 1 kg of meat ( E ) is 7000 J. Formula used: Write the expression energy in terms of power and time duration as follows. E = P Δ t (1) Here, E is the energy required to deposit in a 1 kg of meat, P is the power in the electron beam, and Δ t is the turned on duration of the electron beam to deposit the given amount of energy. Write the expression for the power in the electron beam as follows. P = I Δ V (2) Here, I is the beam current, and Δ V is the potential difference applied for the electron beam. Write the expression for energy of the electrons in the electron beam as follows. E beam = Q Δ V (3) Here, Q is the charge of one electron, which is 1.602 × 10 − 19 C . Explanation: From equation (2), substitute ( I Δ V ) for P in equation (1), E = ( I Δ V ) Δ t Rearrange the expression for potential difference applied to the electron beam as follows. Δ V = E I Δ t (4) Write the conversion factor to convert the energy of the electrons in the beam from electron volts to the Joules as follows. 1 eV = 1.602 × 10 − 19 J Multiply with 10 6 on both side of the expression as follows. ( 1 eV ) ( 10 6 ) = ( 1.602 × 10 − 19 J ) ( 10 6 ) 1 MeV = 1.602 × 10 − 13 J Multiply with 10 on both side of the expression as follows. ( 1 MeV ) ( 10 ) = ( 1.602 × 10 − 13 J ) ( 10 ) 10 MeV = 1
