The answer is (F) 4. (5pts) A circular metal disk of radius R=0.5m rotates counter-clock-wise with period

The answer is (F)

Transcribed Image Text:

4. (5pts) A circular metal disk of radius R=0.5m rotates counter-clock-wise with period 0.ls about an axis through its center perpendicular to the disk (Fig. 6). The disk rotates in a uniform magnetic field B = (-0. 12)T. The magnitude of the electric field at 7 = î is E (in SI unit). What is E and the direction of the electric field at this position? (A) E = 0 (B) 0 < E< 1, +â (C) 0 < E < 1,-î, (D) 0 < E < 1,+ŷ, (E) 0 < E < 1,-ŷ, (F) 1< E < 2, +â (G) 1 < E < 2,-î, (H) 1 < E < 2, +ŷ, (J) 1< E < 2,-ŷ, (K) 2< E < 3,+x (L) 2 < E < 3,-î, (M) 2 < E < 3, +ŷ, (N) 2< E < 3,-ŷ, (0) 3< E,+â (P) 3 < E, -x, (Q) 3 < E, +ŷ, (R) 3< E, -ŷ, 4.
