B) Irregular
Good luck on the rest :D
We are given with the data that the angle of velocity is above the negative axis. hence, the angle lies in the second quadrant with negative x axis and positive y axis. In this case, the x component is -12 cos 60 equal to -6 m/s while the y-component is 12 sin 60 equal to 6 sqrt of 3 m/s.
Answer:
magnetic field strength is 0.315852 T
Explanation:
Given data
thick = 0.103 mm = 0.103 × 10^-3 m
charge-carrier density = 1.11 × 10^25 m^–3
hall voltage = 3.47 mV = 4.99 × 10^-3 V
current = 2.89 A
to find out
magnetic field strength
solution
we will apply here magnetic field strength formula i.e
magnetic field strength = hall voltage × charge-carrier density × magnitude of charge electron × thick / current
here put all these value and magnitude of charge electron is 1.6×10^-19 C
magnetic field strength = hall voltage × charge-carrier density × magnitude of charge electron × thick / current
magnetic field strength = 4.99 × 10^-3 × 1.11 × 10^25 × 1.6×10^-19 × 0.103 × 10^-3 / 2.89
magnetic field strength = 0.912811 / 2.89
magnetic field strength is 0.315852 T
