Nettet30. des. 2016 · 2. Electric field lines can be discontinuous. Consider an infinite sheet of uniform charge density. The field is constant on either side of the sheet, but abruptly switches direction when moving from one side to the other. The field is discontinuous at the location of the sheet. A more proper statement would probably be: "If we only allow ... NettetVerified by Toppr. An electric field line is an imaginary line or curve drawn from a point of an electric field such that tangent to it (at any point) gives the direction of the electric field at that point. Properties : 1. Electric field lines starting from positive charge and terminating at a negative charge. 2.

NettetCharge dq d q on the infinitesimal length element dx d x is. dq = Q L dx d q = Q L d x. This dq d q can be regarded as a point charge, hence electric field dE d E due to this element at point P P is given by equation, dE = dq 4πϵ0x2 d E = d q 4 π ϵ 0 x 2. ⇒ dE = (Q/Lx2)dx 4πϵ0 ⇒ d E = ( Q / L x 2) d x 4 π ϵ 0. NettetAs a concrete example, consider Figure 20.16, which shows a charge q moving with velocity →v through a magnetic field →B between the poles of a permanent magnet. The magnitude F of the force experienced by this charge is. F = qvBsinθ, 20.4. where θ is the angle between the velocity of the charge and the magnetic field. thread command solid edge

Nettet8. aug. 2016 · The answer is obvious if you look at the formula, ∮ E →. d S → = q ϵ o. For a symmetric distribution, you ca always take a surface such as a sphere, cylinder where the electric field is equal everywhere. If the field is equal everywhere, you can pull the field parameter out of the integral and you will be left with, NettetA field line is an integral curvefor that vector field and may be constructed by starting at a point and tracing a line through space that follows the direction of the vector field, by … NettetElectric field lines.
