29. An electron is travelling at 100 km/s parallel to a
long straight horizontal conductor a distance of 3.00 cm
from the conductor. A current of 12.0 A runs through
the wire as the electron travels parallel to it, in the same
direction as the electron's velocity. Find the strength
of the external electric field that will prevent the elec-
tron from deviating from its original path. Express your
answer in V/m.
a) What would the Hall voltage be (in µV) if a 2.40 T field is applied across a 13-gauge copper wire (1.829 mm in diameter) carrying a 22.0 A current? (Assume the free charge density of copper is 8.342 ✕ 1028 e−/m3.)
b)A mirror hangs 1.62 m above the floor on a vertical wall. A ray of sunlight, reflected off the mirror, forms a spot on the floor 1.12 m from the wall. Later in the day, the spot has moved to a point 2.50 m from the wall.
What is the change in the angle of elevation of the Sun, between the two observations?
c)Components of some computers communicate with each other through optical fibers having an index of refraction n = 1.45. What time in nanoseconds is required for a signal to travel 0.180 m through such a fiber?
