Q1 ‚A Q2 Q3 1 cm F---

answer the following

There are two concentric cylinders with R1= 0.0056 m and R2= 8R1 with a length of 6.1m. The internal cylinder charge is q=2.7nC and uniformly distributed, the external one is -3q also uniformly distributed. How much is the electric field at r= 4.4R1. Express your answer in N/A to three significant figures.

A cube has positive charge +Q in all corners except for one, which has a negative point charge - Q. Let the distance from any corner to the center of the cube be r. What is the magnitude and direction of the of electric field at the center of the cube (point P)?

Given the two charged particles shown in the figure below, find the electric field at the origin. (Let q₁ = -24.00 nC and 92 = 8.00 nC. Express your answer in vector form.) E E = N/C -4 -2 y (cm) 92 2 91 4 x (cm)

Show that for a charged circular ring of radius a and total charge Q, the electric field anywhere inside the plane of the ring would be zero if the electric field was inversely proportional to r not r2. Your answer is partly verbal and graphical.
