There is a constant homogeneous electric field of `100 Vm^-1` within the region `x=0 and x=0.167 m` pointing in x-direction. There is a constant homogeneous mangetic field B within the region `x=0.167 m and x=0.334 m` pointing in the z-direction. A proton at rest at the origin is released in positive x-direction. Find the minimum strength of the magnetic field B, so that the proton is detected back at `x=0, y=0.167 m.` (mass of proton `= 1.67 xx 10^(-27) kg)`
