A proton moving at speed 300 km/s flies into a homogeneous electric field of width 1 m and field intensity 500 V/m at an angle of 60 deg to the electric field lines. At what time will the proton leave the area of a homogeneous electric field? Neglect the effects of gravity. Take the ratio of proton charge to its mass equal to 9.6 * 10^7 C/kg.
