coordinate vector field

Displacement vector is a vector which gives the position of a point with reference to a point other than the origin of the coordinate syste..

Fixed vector is that vector whose initial point or tail is fixed. It is also known as localised vector. For example, The initial point of a position vector is fixed at the origin of the coordinate axes. So, position vector is a fixed or lo..

Displacement Vector - Displacement vector is a vector which gives the position of a point with reference to a point other than the origin of the coordinate system. Let a particle at a point P at an instant of time t, move to another point Q at time t l . The ..

It was mentioned earlier that, displacement vectors are added to displacement vectors, or velocity vectors are added to velocity vectors. Just as it is meaningless to add scalar quantities of different kinds, such as mass and temperature, so also it is ..

The three rectangular unit vectors are illustrated in the figure. Basically these unit vectors are used to specify the positive X, Y, Z directions respectively. Note that need not be located at the origin. Like all vectors, they can be translated anywher..

Zero vector or null vector is a vector which has zero magnitude and an arbitrary direction. It is represented by . If a vector is multiplied by zero, the result is a zero vector. It is important to note that we cannot take the above result to be a n..

The gravitational field intensity at a point is defined as the force experienced by a unit mass placed at that poin..

Electric field produced by a dipole is known as dipole field. Let +q and -q be equal and opposite point charges separated by a small distance 2l. The strength of an electric dipole is measured by a vector quantity known as electric dipole moment known as electric dipo..

Summary - Electric charge is a basic property of all matter. Unlike charges attract, like charges repel. Conductor allow flow of electric charges through them while insulators don't. Electric charges have three basic properties (a) Additivity (b) Quantisation (c) Conservation Coulomb's law: the Ele..
