Question
Constants Peradic Table Part A Laboratory scientists have created the electric and magnetic fields shown in the figure. (Figure 1) These fields are also seen by scientists that zoom past in a rocket traveling in the z-direction at 1.0 x 106 m/s. Assume that B = 060 T and E- 1.1 106 V/m According to the rocket scientists, what angle does the electric field make with the axis of the rocket? Express your answer using two significant figures 0 above the axis of the rocket Figure 1 of 1 Submit Previous Answers Request Answer X Incorrect; Try Again; 2 attempts remaining 1.0 × 106 m/s Provide Feedback 45Explanation / Answer
Given,
V = 1 x 10^6 i m/s
B = 0.6 k T
E = 1.1/sqrt(2)i + 1.1/sqrt(2)j = 0.778 x 10^6 i + 0.778 x 10^6 j
Er = E + (v x B)
= (0.778 x 10^6i + 0.778 x 10^6j)((1 x 10^6i) x (0.6k))
= (0.778x10^6 i + 0.778x10^6j) - 0.6 x 10^6j
= 0.778 x 10^6 i + 0.178 x 10^6 j
Theta = arctan (0.178/0.778) = 12.89 degree
