32. A cyclotron in which protons are accelerated has a flux density of 1.57T. The variation of frequency of electric field is ( in Hz)
1) 4.8 x 10⁸            2) 8.4 x 10⁸
(3) 2.5 x 10⁷           4) 4.8 x 10⁶

33. Cyclotron is adjusted to give proton beam, magnetic induction is 0.15 wbm^​-2 and the extreme radius is 1.5 m. The energy of emergent proton in MeV will be. 
1) 34.2         2) 3.42         3) 2.43          4) 24.3
