Electric field due to finite line charge at perpendicular distance Positive charge QQ is distributed uniformly along y-axis between y=−ay=−a and y=+ay=+a. We have to find electric field due to line charge at point PP on the x-axis at a distance xx from the origin. Figure below...
Definition:An electric field line is defined as a region in which an electric charge experiences a force. The charged objects can either be positive or negative, the opposite charges attract each other and like charges repel. The field lines are visual representations of the electric field creat...
Surface chargeGeometrical methodsA geometrical approach to calculate the electric field due to a uniformly charged rod is presented. The result is surprisingly simple and elegant. Using pure geometrical quantities like length and angle, the direction of the electric field in this charge configuration ...
Positive electric charge Q is distributed uniformly along a line (you could imagine it as a very thin rod) with length 2a, lying along the y-axis between y = -a and y = +a. A point p lies at x along x-axis. Find the electric field at point P. Linear charge density, $\lambda$...

4.3Regulating internal electric field According to the charge separation property of BiOCl, its unique layer structure is favorable for inducing the internal electrostatic field along the [001] direction, which is beneficial to enhance the photocatalytic performance. Taking advantage of theinternal electric...
Field-changes due to lightn i ng discharges are investigated by simultaneous recording by means of electrostatic fluxmeter and amplifier oscillograph. It has been made clear that the leader to the 1st return stroke is always a stepped leader, because successive pulses having regular intervals correspon...
