Question

This problem explores how a current carrying wire can be accelerated by a magnetic feld. You will use the ideas of magnetic flux and the EMF due to change of fux through a loop. Note that there is an involved follow-up part that will be shown once you have found the answer to Part B. Figure 1 of 1 Under these idealized conditions the rod will experience constant acceleration and the velocity of the nod wil in The rod will accelerate indefinitely with acceleration proportional to its (increasing volocity Submit Hints My Answers Give Up Review Part Correct Part C What is the acceleration a,(t) of the rod? Take m to be the mass of the rod, Express your answer as a function of V, B,the velocity of the rod (t), L, R and the mass of the rod m. a,(t) Submit Hints My Answers Give Up Review Part Incorrect: Try Again; 8 attempts remaining Part D

Explanation / Answer

w = 2pi / T

= 2 pi / (4.40 x 10^-2)

= 142.8 rad/s

(C) induced emf = N A B w

= 230 x (11.7 x 10^-4) (5.50 x 10^-5) (142.8)

= 2.11 x 10^-3 Volt
