Question

1 Approved Answer

V = N B l v where N is the number of turns in the coil, B is the magnitude of the magnetic field, l

V=NBlv
where N is the number of turns in the coil, B is the magnitude of the magnetic field, l is the length of the side of the coil that is perpendicular to the velocity direction and lowercase v is the velocity of the coil. If you make a plot of Voltage vs velocity, the slope of that graph will be NBI. Add calculations to the cell block below to find the predicted value of the slope, along with its uncertainty. You may use either the functional or calculus method to find the uncertainty. Make sure that your answer has units and the appropriate number of digits.
import numpy as np
# Calculate the slope of a Voltage vs velocity graph along with the uncertainty
# in the slope
N=100 # The number of turns is exactly known and doesn't have an uncertainty
B=0.032# Teslas
Bunc =0.003# Teslas
l=0.174#m
lunc =0.002#m
# Fill in the calculation for the slope and the uncertainty in the slope
slope = NBI
# Warning: the lengths l and lunc are given in cm, make sure you convert to the correct
# units!
# Change the print statement below to output the correct number of digits for
# both the slope and its uncertainty
# Add the correct units for slope to the print statement.
print('slope ={:,3f} lu00B1{:,3f}', format(slope, slopeunc))
