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 .

A beam of non-relativistic charged particles moves without deviation through the region of space A where there are transverse mutually perpendicular electric and magnetic fields with strength E and induction B. When the magnetic field is switched off, the trace of the beam on the screen S shifts by Delta x . Knowing the distance a and b, find the specific charge q/m of the particles.

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.

A narrow beam of identical ions with specific charge q/m, possessing different velocities, enters the region of space, where there are uniform parallel electric and magnetic fields with strengths E and B , at the point O. The beam direction coincides with the x-axis at the point O. A plane screen oriented at right angles to the x-axis is located at a distance I from O.
