Multiplication of Vectors by Real Numbers, i.e., Scalar Multiple of a Vector
The multiplication of a vector by a real number assumes a lot of significance in such statements as - velocity of car B is double the velocity of car A l..
Multiplication of a matrix by a scalar
Let A=[a i j ] be an m x n matrix and k be any number called a scalar. Then the matrix obtained by multiplying every element of A by k is called the scalar multiple of A by k and is denoted by kA. Thus, kA = [k a i j ] m x ..
Multiplication of a Matrix by a Scalar
When a matrix is multiplied by a scalar factor k, then each element of the matrix is multiplied by ..
Multiplication of a Matrix by a Scalar

When a matrix is multiplied by a scalar factor k, then each element of the matrix is multiplied by ..Dot Product of Vectors and the Resolution of a Vector
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 i..

Multiple Charges
Multiple Charges - Coulomb's law describes only the interaction of two point charges. Experiments show that when two charges exert forces simultaneously on a third charge, the total force acting on that charge is the vector sum of the forces that the two charges would exert indi..

Coulomb's law describes only the interaction of two point charges. Experiments show that when two charges exert forces simultaneously on a third charge, the total force acting on that charge is the vector sum of the forces that the two charges would exert individually. This importan..
Addition or Composition of Vectors
Scalars can be added algebraically. However, vectors do not obey the ordinary laws of algebra. This is because vectors possess both magnitude and direction. Vectors are added geometrically. The process of adding two or more vectors is known as..
See what our Users say :
Tutors are very well educated who knows what they are doing and is very good at math. Also I like the way they teach me - Baker
They always come through for me never fails me,great tutors,cant say thank u enough,lets hope we score big on the exams :-) - Jenna
The tutor made sure i was learning and made sure i was paying attention, superbbbb session. Thank u
This is very helpful and explains everything thoroughly. when asked to do problems slowly, tutors did them very thoroughly and even went extra mile to explain how and why with text - I just bow down to Turor Vista
