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.
