vector force fields

Michael Faraday (1791 - 1867) introduced the idea of lines of forces. They are nothing but a way of pictorially mapping the electric field around a configuration of charges. It is the curve drawn in such a way that the tangent to it at each point is in the direction of the net h..

Bonding in a complex ion is due to electrostatic interactions between the positively charged nucleus of the central metal ion and electrons in the ligands i.e., attractive as well as repulsive interactions. (i) The attractive forces will arrive due to the positive metal ion and the negati..

They are nothing but a way of pictorially mapping the electric field around a configuration of charges. It is the curve drawn in such a way that the tangent to it at each point is in the direction of the net field at the point. An arrow on the lines of force is a..

Potential Energy of a Single Charge - In the previous chapter, we learnt about specific charge, its location, and its electric field, but here we are considering the potential energy of a charge, in an external field. Consider an external electric field 'E' produced by..

Calculations of electric field intensity are of tremendous importance due to the technological applications of electric forces. To determine the trajectories of electrons in a T.V. tube, in an accelerator used in cancer radiotherapy, or of charged particles in a semiconductor el..

Magnetic Field Due to a Solenoid - A solenoid is a long coil (shaped like a cylinder) containing a large number of close turns of insulated copper wire. The figure above shows a solenoid SN whose ends are connected to a battery B through a switch X. When a current is passed through a sole..

Rules for Determining the Direction of Magnetic Field - The direction of magnetic field around a current carrying conductor can be determined by using one of the laws given here. Rule Pictorial Representation Right Hand Thumb Rule Imagine that you are holding the conductor in yo..

Mapping of Magnetic Lines of Force - A pictorial representation that gives the direction of the magnetic field at various points in a magnetic field is called a map of the magnetic field Let us now map the magnetic field by using a compass Fix a she..

A body on which two or more forces act is said to be in equilibrium if there is no change in its state of rest or of uniform motion. The condition necessary for equilibrium is that the vector sum of forces acting on the body should be zero. i.e., This also implies that..

If two or more forces act on the same body, then the acceleration of the body can be written as the vector sum of the individual accelerations produced by each force. The acceleration of the body can be better expressed as the acceleration caused by the res..
