- The following charges distributions are present in free space as shown in Figure, point charge 6 nC at P(2.0,6). a uniform infinite line charge density 1.5 nCm at x-2, y- 3, and infinite surface charge density 0.1 nCm atx2. the electric field at origin due to the point charge only is le charge 4.427a-1281a 475 ax ONone of Thesearrow_forwardi need the answer quicklyarrow_forwardCould you please explain it?arrow_forward
- In the figure particles 2 and 4, of charge -e, are fixed in place on a y axis, at y₂ = -8.38 cm and y4 = 4.19 cm. Particles 1 and 3, of charge - e, can be moved along the x axis. Particle 5, of charge +e, is fixed at the origin. Initially particle 1 is at x₁ = -8.38 cm and particle 3 is at x3 = 8.38 cm. (a) To what x value must particle 1 be moved to rotate the direction of the net electric force Fnet on particle 5 by 30° (b) With particle 1 fixed at its new position, to what x value must you move particle 3 to rotate back to its original counterclockwise? direction?

A rod of semiconducting material of length L = 7 m and cross-sectional area A = 2.5 mm2 lies along L. The material obeys Ohm's law, and its resistivity varies along the %3D the x-axis between z = 0 and z = rod according to p= po 1 where po L? 2.5 x 10 4N. m. The end of the rod at a = 0 is at a %3D potential Vo = 40 V greater than the end at a = L. A) What is the total resistance, in units of 2, of the rod? Answer: B) What is the current, in units of miliamperes, in the rod? Answer: C) What is the electric potential, in units of Volt, in the rod at z = L/2? Answer:arrow_forwardA volume charge density is known to be Delta(n, deg, z) in cylindrical coordinates.
