But there is a net fied lines that originate inside the sphere and exiting it. Because at microlevel the charge is partially inside the sphere.
Hi, Find the expression of the force of repulsion between the two charges in terms of q. F = k q(Q-q) / r2 To get maxmum value of force, dF/dq = 0, So, (k/r2) (Q – 2q) = 0 or q = Q/2...
Hi, Coulombic force, F = k q2r^ / r2 r^ = (r2– r1)/ r =(i + 2j – 2k) / 3 Now, put this value of r^ in the force equation to get the force vector. The ‘i’ component of the force...
In this case, first you calculate the flux through cube, it would be sum of flux through the one surface and flux through the rest. Flux through the cube wil be q/8Ç,= 3xFlux through one wall +...
Hi Student, Please in detail explain your...
The flow of charge depends on potential difference and is in turn depends on capacitance, as potential difference varies exponentially wrt time, it theoratically takes infinite time.
Hi, Yes, it would travel in the straight line but with variable acceleration depending on its position in the electric field....
Hi, If you have looked at the question carefully, all the four branches are between ponts A and B. Two branches have capacitance C/2 (C and C in series) each and other two branches have capacitance C...
Ceq is 2C
There is no particular way of describing the direction of dipole rather it is hypothetic.But one should know the fact that if lenth is taken as 2L,means it has a specific origion(No matter for ease it...
The 5 capacitances in the mid are forming a wheatstone bridge. So, if a test battery were to be applied, the curent wouldn’t pass through the vertical C in the middle as it is a balanced...
The option is (2) equate both of them to equal potential to get the answer.
Dear student, According to the question, 10 9 electrons move out in 1 sec. So, the charge transferred per unit sec is equal to so, to transfer 1 C charge, the time taken would be equal to Regards
Hi, Two similar charges are stable when they are far away, but when they are brought closer, they become unstable due to increase in potential energy (+ve) But when two unlike charges are brought...
Be the first one to answer
Hiiii I am from tutorsduniya.com .We connect students with teachers on facebook,whats app,etc.You can clear your concepts from teachers .You can ask them anything , you like to, be frank with them,...
Charge on proton is equal to the charge on electron and also equal to atomic no, when this quantity put in an electric field, it flows from higher potential to lower potental. the Capacitor, sometimes...
Dear student, Please post a clear imageof the question. The question is not visible properly....
Three concentric spherical metallic shells A, B and C of radii of a,b and c (c>b>a) have charge densities σ, -σ and σ respectively. The potential of shell B isOptions: 1....
The magnitude of force will vary on the placements of the charged conductors. 1. If the are placed parallel to each other at certain distance, then force between them would be of opposite nature, and...
Its well known concept that outside the conducting charged body, finding the electric field, the body behaves as point charge, Here, we are given that charge is spreaded over the ramp surface only, so...
Using the concept of Coulombian force, calculate the magnitude of charge b. In the second case, assume the charge to be 'q' and '4q' and calculate the force between these for the same...
Electron Gun Assembly. The electron gun assembly consists of an indirectly heated cathode, a control grid surrounding the cathode, a focusing anode and an accelerating anode. The sole function of...
Here in the question, charge density is spread over three dimensional arrangement. Since, we are known about the concept of triple integration, so integrating the charge density along x, y and z axes...
