Homework Statement An electron confined in a one-dimensional box is observed, at different times, to have energies of 27 eV , 48 eV , and 75 eV . What is the length of the box? Hint: Assume that the quantum numbers of these energy levels are less than 10. Homework Equations E=h^2n^2/(8mL^2)...

Homework Statement A triple-slit experiment consists of three narrow slits, equally spaced by distance d and illuminated by light of wavelength λ. Each slit alone produces intensity I1 on the viewing screen at distance L. Consider a point on the distant viewing screen such that the path-length...

Ah ok, i got it, thank you.

So I use F = qE + qvXB, they give me the v, B, F, and q since it is a proton. Then i just solve for E right? Where would the angle of 30degrees come into play?

Homework Statement What is the electric field strength at the position of the proton in the figure?(Figure 1) Assume that B = 0.10 T and F = 3.4×10−13N . Figure 1: https://session.masteringphysics.com/problemAsset/1385081/6/35.P29.jpg Homework Equations Honestly I don't know. Since we have a...
