Question

eleetron is moving erpithe magnitude of the force acting on the electron? qular to a 1.0T magnetic field. The electron has a of the f velocity of I x 10 m/s. What (A) 16x 10""N (B) 1.6x 10"2N (C)1.6 x 10-10N (D) 1.6 x 10-9 N 2. The Points A through E on the Figurel represent various distances from the center of the current-carrying wire. Which point experiences the strongest magnetic field? ( ) (A) Point A (B) Point C (C) Point D (D) Point E 3.A wave has a frequency of 100 Hz and a wavelength of 1 m. What is the velocity of the wave? ) (A) 0.01 m/s (B) 1 m/s (C) 10 m/s (D) 100 m/s Figurel A wave of light (a 638 nm) enters a block of material. The wavelength of light within the material is 510 nm. What is the index of refraction of the (A) 0.5 (B) 0.8 (C) 1.2 (D) 1.25

Answer 1

Magnetic field is inversely proportional to the distance from current carrying wire. So It will be maximum near to the current carrying wire.
