Answer:
(I). The motional emf induced between the ends of the segment is
(II). The motional emf is zero.
Explanation:
Given that,
Magnetic field = 0.080 T
Velocity of wire segment = 78 m/s
Component in x direction = 18 m/s
Component in y direction = 24 m/s
Component in z direction = 72 m/s
Length = 0.50 m
We need to calculate the motional emf induced between the ends of the segment
Using formula of emf
Put the value into he formula
(II). If the wire segment is parallel to the y-axis then the angle between B and v is zero.
We need to calculate the motional emf
Using formula of emf
Here,
Hence, (I). The motional emf induced between the ends of the segment is
(II). The motional emf is zero.
