Can a vector with the magnitude of 2 be added to a vector with a magnitude of 3?
5
What magnitude is not possible when a vector of a magnitude of 3 is added to a vector of a magnitude of 4?
A magnitude of less than 1. cw: An absolute magnitude of less than 1.
Why is angular displacement a vector quantity?
Angular displacement is a vector quantity because it has both magnitude and direction. The direction of angular displacement is determined by the axis of rotation and follows the right-hand rule, while the magnitude is given by the angle of rotation. As a vector, angular displacement can be added, subtracted, and resolved into components, making it useful in calculations that involve rotational motion.
What is the physical significance of null vectors?
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 number, the result has to be a vector and here lies the importance of the zero or null vector. The physical meaning of can be understood from the following examples. The position vector of the origin of the coordinate axes is a zero vector. The displacement of a stationary particle from time t to time tl is zero. The displacement of a ball thrown up and received back by the thrower is a zero vector. The velocity vector of a stationary body is a zero vector. The acceleration vector of a body in uniform motion is a zero vector. When a zero vector is added to another vector , the result is the vector only. Similarly, when a zero vector is subtracted from a vector , the result is the vector . When a zero vector is multiplied by a non-zero scalar, the result is a zero vector.
What magnitude is not possible when a vector of magnitude 3 is added to a vector of magnitude 4?

Can a vector be added to a scalar?
No- vector ad scalar are two different things. Scalar consists only of magnitude, whereas vector consists both magnitude and direction.
Is volt a vector quantity?
no volt is not a vector quantity because it has no direction and it can be added or subtracted as scalar quantities. volt in electrostatics is analogous to vertical height in mechanics . vertical height have a value for every place but no direction and height can be added or subtracted as scalar
If a vector of magnitude 3 is added to a vector of magnitude 4 what can the magnitude of the resultant be?

When two equal and opposite vectors are added their resultant vector has zero magnitude what is the direction of this resultant?
The zero-vector has no direction.
Can you add zero in null vector?
no,zero cannot be added to a null vector because zero is scalar but null vector is a vector,although null vector has zero magnitude but it has direction due to which it is called a vector.
If vector B is added to vector A under what circumstances does the resultant vector A plus B have magnitude A plus B. under what circumstances does the resultant vector equals to zero?
if b + a , since a+b equals b + a due to it being commutative . it shud have the same magnitude and direction
A vector of magnitude 3 cannot be added to a vector of magnitude 4 so the magnitude of the resultant is?
