Vectors

Q1:    What is resolution of vector?
Ans:  To resolve a vector into its components is called resolution of vectors. A vector can be resolved in to two components.

Q2:    What is head to tail rule?
Ans:  Two or more vectors can be added by using head to tail rule. According to this rule the head of first vector is joined with the tail of second vector and heat of second vector joins with the tail of third and so on. The resultant vector is directed from the tail of first vector to the head of last vector as shown in fig.
Q3:     Define negative vector?
Ans:   The negative vector (-A) of a vector A is such that it has the same magnitude as that of A but opposite direction.

Q4:     What are rectangular components of a vector?
Ans:    The components of a vector which are perpendicular to each other. The magnitude of the components are 
Fx = Fcos (theeta)               Fy = Fsin (theeta)
