A magnetic field set up using Helmholtz coils (described in Question 16 above) is uniform in a small region and has a magnitude of `0*75T`. In the same region, a uniform electrostatic field is maintained in a direction normal to the common axis of the coils. A narrow beam of (single species) charged particles all accelerated through `15kV` enters this region in a direction perpendicular to both the axis of the coils and the electrostatic field. If the beam remains undeflected when the electrostatic field is `9xx10^5Vm^-1`, make a simple guess so to what the beam contains. Why is the answer not unique?

A magnetic field set up using Helmholtz coils (described in Exercise 4.16) is uniform in a small region and has a magnitude of 0.75 T. In the same region, a uniform electrostatic field is maintained in a direction normal to the common axis of the coils. A narrow beam of (single species) charged particles all accelerated through 15 kV enters this region in a direction perpendicular to both the axis of the coils and the electrostatic field. If the beam remains undeflected when the electrostatic field is 9.0xx10^(-5)Vm^(-1) , make a simple guess as to what the beam contains. Why is the answer not unique ?

A magnetic field, set up using Helmhotlz coils, is uniform, in a small region and has a magnitude of 0.75t . In the same region, a uniform electrostatic field is maintained in a direction normal to the common axis of the coils.
