If the current is perpendicular to the magnetic field then the magnetioc field in this experiment is: F vsI y1.2534x+0.2127 14 12 10 (A) 3.13 x 104 T (B) 0.0313 mT (C) 31.3 mT (D) 0.313 T (E) 31.3 T 10 1 (A) Dept of Applied Physics and Astronomy Physics 2 labFinal Exam Summer iz/s

Explanation / Answer

15) according to junction rule

I1= I +I2

So current flowing through the resistor is

I = I1+ I2

ANSWER is D.
