Assume that the electric potential field in a certain region is given by phi(x, y, z) = a * (x2 + y2 + z2), where a is a constant. Find the electric field vector E(x, y, z) in this region.

Question 1 Four stationary electric charges produce an electric field in space. The electric field depends on the magnitude of the test charge used to trace the field O has different magnitudes but same direction everywhere in space is constant everywhere in space has different magnitude and different directions everywhere in space CANAD

A charge distribution creates the following electric field throughout all space: E(r, 0, q) = (3/r) (r hat) + 2 sin cos sin 0(theta hat) + sin cos p (phi hat). Given this electric field, calculate the charge density at location (r, 0, p) = (ab.c).

Compute the flux of the vector field  F=2xi+2yj through the surface S, which is the part of the surface z=36−(x^2+y^2) above the disk of radius 6 centered at the origin, oriented upward. flux = _____

E ↑ Απεργια This problem checks your understanding of the term in the equation for the electric field due to a point charge, Consider a charged particle at a point S whose coordinates are (4 m, 2 m, 6 m). We would like to find the electric field vector at a point P whose coordinates are (7 m, 8 m, 1 m). The "unit vector" is a vector that points from S to P that has length of 1 (or "unity"). What is its y component, in meters? (Report your answer to one decimal place.)

Find the position vector r(arrow) that points from Proton 1 to the Proton 2, its magnitude |r(arrow)∣, and its unit vector, r(hat). Look at the image for the question.

Consider a long, cylindrical charge distribution of radius R with a uniform charge density ρ. Find the electric field at distance r from the axis, where r < R.

An electric field of magnitude 464 V/m passing through a flat square plate of length 0.644 m on a side makes an angle of 63.6 degrees with the surface of plate. Determine the electric flux passing through the surface of the square plate. (Hint: the angle given here is the angle that the field makes with the surface, not with the area vector. In what direction does the area vector of a surface point relative to that surface?)
