Question

The projection of a vector in a particular direction is called [ ]
a) Magnitude of vector
b) Direction of vector
c) Component of vector
d) Resultant of vector

Answer 1

c Component of vector

Answer 2

The projection of a vector in a particular direction is called Direction of vector

Explaination:

The vector projection is the vector produced when one vector is resolved into two component vectors, one that is parallel to the second vector and one that is perpendicular to the second vector. The parallel vector is the vector projection.

Here is the vector projection formula our calculator uses to find the projection of vector a onto the vector b: $p = (a\cdot b / b\cdot b)\cdot b$. The formula utilises the dot product, a·b, of the vectors, also called the scalar product.
