Verification on problem 7?

6.A 0 CO 5.40E-6 DO 5.73E-6 EC This problem can't be done, because Ampere's Law isn't true for octagons. 5 point (s) What is the speed of a beam of electrons when the simultaneous influence of an electric field of magnitude E and a magnetic field of magnitude B, with both fields perpendicular to the beam and to each other, produces no deflection of the electrons? qEB EO None of the above 5 point(s) It is known that birds can detect the earth's magnetic field, but the mechanism by which they do this is not known. It has been suggested that perhaps they detect a motional emf as they fly north to south, but it turns out that the induced voltages are small compared to the voltages normally encountered in cells, so this is probably not the mechanism involved To check this out, calculate the induced yoltag for urild

Explanation / Answer

Force due to magnetic field = qVB
Force due to electric field = qE

qE=qVB

E=VB


C) V= |E/B|

V= E/B
