Any two vectors are said to be “equal vectors” , when they have same magnitude and same direction. In all other cases apart the above one case , they are called “unequal vectors.” So,
If two vectors have same magnitude but different directions
, they are called unequal vectors.
What are the 3 types of vectors?
- Zero Vector.
- Unit Vector.
- Position Vector.
- Co-initial Vector.
- Like and Unlike Vectors.
- Co-planar Vector.
- Collinear Vector.
- Equal Vector.
What do you mean by equal vector?
Two or more vectors are equal
when they have the same length
, and they point in the same direction. Any two or more vectors will be equal if they are collinear, codirected, and have the same magnitude. … In other words, two or more vectors are equal if their coordinates are equal.
Can two vectors of unequal magnitude?
Yes, two vectors of equal magnitude that are pointing in opposite directions will sum to zero.
Two vectors of unequal magnitude can never sum to zero
. If they point along the same line, since their magnitudes are different, the sum will not be zero.
What is a null vector in physics?
In mathematics and physics, a vector is an element of a vector space. … The null vector is
a vector having magnitude equal to zero
. A null vector has no direction or it may have any direction. Generally a null vector is resultant of two equal vectors in opposite directions.
What is an example of a biological vector?
Vectors are frequently arthropods, such as
mosquitoes, ticks, flies, fleas and lice
. Vectors can transmit infectious diseases either actively or passively: Biological vectors, such as mosquitoes and ticks may carry pathogens that can multiply within their bodies and be delivered to new hosts, usually by biting.
Is vector positive or negative?
Vectors are only negative with respect
to another vector. … The magnitude, or length, of a vector, cannot be negative; it can be either be zero or positive. The negative sign is used here to indicate that the vector has the opposite direction of the reference vector.
What are the 2 types of vector?

Can bacteria be used as a vector?
Bactofection: bacteria are used as a vehicle/vector
to transport the genetic information into the eukaryotic cell
. (a) Transformed bacteria that contain plasmids carrying the transgene are applicated into the target tissue.
What is the difference between position vector and unit vector?
Position is a vector quantity. It has a magnitude as well as
a direction
. The magnitude of a vector quantity is a number (with units) telling you how much of the quantity there is and the direction tells you which way it is pointing. A unit vector is a direction indicator.
Can three unequal vectors add to zero?
Since a scalene triangle exists,
three unequal vectors can add up to zero
. The conditions for three vectors to form a triangle are: The sum of magnitudes of any two of them must be greater than the magnitude of third. magnitude of sum of two vectors must be equal to the magnitude of third.
Can two vectors with unequal lengths ever add to zero?
No. The sum of two vectors
can only be zero if they are in opposite directions
and have the same magnitude.
Can you add two unequal vectors and get zero?
No, it is not possible to obtain zero
by adding two vectors of unequal magnitudes. From the above equation, we can say that the resultant vector is zero (R = 0) when the magnitudes of the vectors and are equal (A = B) and both are acting in the opposite directions.
Do you mean by null vector?
A null vector is a
vector that has magnitude equal to zero and is directionless
. It is the resultant of two or more equal vectors that are acting opposite to each other.
What is null vector example?
This null vector will have zero magnitude and no direction. A real life example would be,
two people pushing the cars in opposite directions with the same or equal force
, or two people pulling a rope from opposite sides with the same or equal forces.
What is null and unit vector?
Zero or null vector – definition
A vector having zero magnitude (arbitrary direction) is called the null (zero) vector. … Unit vector is a
vector of unit length
. If u is a unit vector, then it is denoted by u^ and ∣u^∣=1. For eg:- v=i^+0j^+0k^ Then v^ is a unit vector, since ∣v^∣=1.
