The correct option for the statement “The nucleus of an electrically neutral iron atom contains 26 protons. How many electrons does this iron atom have?”

Answer to Problem 6RAT
The correct option for the statement “The nucleus of an electrically neutral iron atom contains 26 protons. How many electrons does this iron atom have?” is option (b).
Explanation of Solution
Iron atom is present in the eighth group of periodic table. The atomic number of iron atom is 26 and its
Iron atom is electrically neutral, so for this condition, the number of electrons in the iron atom will be similar to the number of protons present in its nucleus. Thus the number of electrons present in iron atom will be 26.
Conclusion:
Therefore, the correct option for the statement “The nucleus of an electrically neutral iron atom contains 26 protons. How many electrons does this iron atom have?” is option (b).

- An electromagnetic wave is traveling through vacuum in the positive x direction. Its electric field vector is given by E=E0sin(kx−ωt)j^,where j^ is the unit vector in the y direction. If B0 is the amplitude of the magnetic field vector, find the complete expression for the magnetic field vector B→ of the wave. What is the Poynting vector S(x,t), that is, the power per unit area associated with the electromagnetic wave described in the problem introduction? Give your answer in terms of some or all of the variables E0, B0, k, x, ω, t, and μ0. Specify the direction of the Poynting vector using the unit vectors i^, j^, and k^ as appropriate.
