electrostatic work

The electrostatic potential is defined as the work done in bringing a single positive charge from infinity to a point (Any point outside the electric field or space is called infinite point). The unit of potential is volt (symbol V..

Electrostatic Potential - The electrostatic potential is defined as the work done in bringing a single positive charge from infinity to a point in the electric field. Any point outside the electric field or space is called infinite point. The unit of potential is volt ..

Electrostatic Potential - When a force acts on a particle that moves from a point 'a' to a point 'b' the work done by the force is given by the integral where is infinitesimal displacement along the particles path and q is the angle is the angle and at each point along the path...

Photocopier moves a document from the handler to the glass plate, where the pattern of the image is projected by lamps, mirrors and lenses onto a photoreceptor belt (or drum). The electrostatic charge on the belt fades in areas receiving light from the projected image. Magnetic rollers b..

. Let us push a box on a table (a rough horizontal surface). The motion of the box is opposed by the force of friction. The force of friction and the displacement of the object always make an angle 180 o and hence, the work done by the frictional force is always negative. When a positive ..

: is the work done at a point by an external agent in moving a unit positive charge from infinity to a given point against the electrostatic field. ..

Potential Energy: is the work done at a point by an external agent in moving a unit positive charge from infinity to a given point against the electrostatic fiel..

Energy Stored in a Capacitor - While charging a capacitor, a battery transfers positive charge from negative to the positive plate. So some work is done in transferring this charge, which is stored in the capacitor in the form of electrostatic energy. This energy can be recovere..

2 due to q 1 . where 'r 1 2 ' is the distance between points 1 and 2. As the electrostatic force is conservative, the work done is stored as potential energy and is given by The potential 'V' would be same, even if the charge q 2 is brought from infinity to a point first..
