A ring has a radius of 71 cm. It has 10 more protons than electrons. This net charge is distributed uniformly over it. What is the electric field at point P, which is on the axis of the ring, and 83 cm from its center? I think you use the equation: (8.99*10^9)* (zQ) / ((z^2+R^2)^3/2)

Aladder that is 30 ft long needs to reach 27 ft up a building. what should the angle of the vertical be?

In the diagram, points d and e are marked by drawing arcs of equal size centered at b such that the arcs intersect ba and bc. then, intersecting arcs of equal size are drawn centered at points d and e. point p is located at the intersection of these arcs. based on this construction, m , and m
