Table P29.70 shows measurements of a Hall voltage and corresponding magnetic field for a probe used to measure magnetic fields.
(a) Plot these data, and deduce a relationship between the two variables.
(b) If the measurements were taken with a current of 0.200 A and the sample is made from a material having a charge-carrier density of 1.00 x 1026/m3, what is the thickness of the sample?

Table P29.70 shows measurements

Table P29.70 19 28 42 50 61 68 79 90 102 0.00 0.10 0.20 0.30 0.40 0.50 0.60 0.70 0.80 0.90 1.00
