(I) What is the magnitude of the electric force of attractionbetween an iron nucleus (q = +26e) and its innermostelectron if the distance between them is 1.5 x 10 -12m ?
A charge q is uniformly distributed on a thin rod of mass m and length I that stays at rest in free space. Two regions of uniform electric field of intensity E are created on both sides of the rod as shown in the figure. In the region of width L where the rod is initially placed, there is no electric field. Now the rod is projected along its length so that it cannot enter completely into any of the regions of electric field. Find period of oscillations of the rod as a function of the maximum distance xm entered by a leading end of the rod into a region of electric field.
Hello, Though I can derive the Taylor series of 1/(1-x), I cannot prove that the x needs to be x << 1. Could you please help me with that? In addtion, how do I derive the formula for the electric field as indicated in (b)? I guess that the x is d/z... but how I can connect this info with the (a) to apply 1/(1-x) Taylor series?
The field due to two parallel plates, the left with a negative surface charge density of −6.0 C/m2 whilethe sheet on the right has a positive surface charge density of +9.0 C/m2is given below. Suppose the plates were spaced 0.0020 m apart. We found that, using Gauss’s law that, independent of this distance, • In I the net field points to the left and has magnitude |Enet| = 1.69 × 1011 N/C.• In region II, between the plates, the field has magnitude 8.47×1011 N/C and points to the left• In III it points to the right and has magnitude |Enet| = 1.69 × 1011 N/C.
Hello, I understand that to calculate the net charge in the shell, I need to integrate the equation from 4 cm to 6 cm with volume charge density times 2 * pi * r * dr. However, since the problem here provides me with a novel expression of p = b/r, I am a bit lost... Could you please tell me how I can solve such problem?
