A proton beam passes without deviation through a region of space where there are uniform transverse mutually perpendicular electric and magnetic field with `E` and `B` Then the beam strikes a grounded target. Find the force imparted by the beam on the target if the beam current is equal to I .

A non-relativistic proton beam passes without deviation through a region of space where there are uniform transverse mutually perpendicular electric and magnetic fields with E= 120 kVm^-1 and B=50 mT. Then the beam strikes a grounded target. Find the force which the beam acts on the target if the beam current is equal to i=0.8 mA . Mass of protons = 1.67xx10^(-27) kg .

Protons move rectilinearly in the region of space where there are uniform mutually perpendicular electric and magnetic fields E and B . The trajectory of protons lies in the plane xz as shown in the figure and forms an angle 9 with x-axis. Find the pitch of the helical trajectory along which the protons will move after the electric field is switched off.

Non-relativistic protons move reactilinearly in the region of space where there are uniform mutually perpendicular electric and magnetic fields with E and B. The trajectory of the protons lie in the plane X-Y as shown in Fig. 1.107 and forms an angle phi with X-axis. Find the pitch of the helical trajectory along which the protons will move after the electric field is switched off.

A beam of electrons passes undeflected through uniformly perpendicular electric and magnetic fields. If the electric field is switched off, and the same magnetic field is maintained then the electrons move:

An electron enters a region where magnetic field (B) and electric field (E ) are mutually perpendicular, then
