A charged particle moves through a region of space that has both a uniform electric field and a uniform magnetic field. What is the condition for these fields in order for the particle to move through this region at a constant velocity? Does the answer depend on the sign of the particle’s electric charge?

Guiana dolphins are one of the few mammals able to detect electric fields. In a test of sensitivity, a dolphin was exposed to the variable electric field from a pair of charged electrodes. The magnitude of the electric field near the sensory organs was measured by detecting the potential difference between two measurement electrodes located 1.0 cm apart along the...
