​pls solve attached Qno. ​ 3. A proton is moving with uniform velocity in x-z plane at an angle of 300 with x-axis, in the presence of an electrostatic field É = (4 kV/m)j and magnetic field g = (50 mT)k. Find the pitch of the helical trajectory followed by the proton (approximately to the nearest integer in crn) when the electric field is switched off. Mass of proton is 1.67 x 10-27 kg. o x z
