cross fields

What do you mean by crossed fields?

In a region of crossed fields as shown, the strength of electric field is E and that of magnetic field is B. Three positively charged particles with speeds V_(1), V_(2) and V_(3) are projected and their paths are shown. From this it implies that

In Thomson's experiment for determining e//m the potential different between the cathod and the anod (in accelerating coloumns ) is same as that between the deflecting plates (in the regions of crossed field ) . If the p.d is doubled , by what factor should the magnetic field be increased to ensure that the electron beam remains undeflected

What is the total force on a moving charge in a cubical region of cross magnetic and electric fields?

Electrons taveling at a velocity of 2.4xx10^(6) ms^(-1) enter a region of crossed electric and magnetic fields as shoen in Fig. If the electric field is 3.0xx10^(6) Vm and the flux density of the magnetic field is 1.5 T, the electrons upon entering the region of the crossed fields will

The number of electric field lines crossing an area DeltaS is n_1 when Delta vecS||vecE , while the number of field lines crossing the same area is n_2 when DeltavecE makes an angles of 30^@ with vecE . Then

The area of a rectangular field is 48 m^2 and one of its sides is 6m. How long will a lady take to cross the field diagonally at the rate of 20 m/minute?
