Why is it necessary to place the arrow head of the vector in the terminal?
Placing the arrowhead at the terminal point of a vector indicates the direction in which the vector is acting. Without the arrowhead, the vector would be ambiguous and could be interpreted in multiple directions. The arrowhead helps to clearly define the magnitude and direction of the vector.
Is it possible for flux to have a negative value?
Yes, it is possible for flux to have a negative value. This occurs when the magnetic field and the area vector are in opposite directions, leading to a negative flux value.
Is it possible for electric flux to have a negative value?
Yes, electric flux can have a negative value if the electric field and the area vector have opposite directions.
Can the directions of velocity and displacement of a particle be different?
Yes, the directions of velocity and displacement of a particle can be different. Velocity is a vector quantity that includes both speed and direction, while displacement is a vector quantity that represents the change in position. Therefore, it is possible for a particle to move in one direction while its displacement changes in another direction.
What is vector sum?
The vector sum is the result of adding two or more vectors together. It is found by combining the magnitudes and directions of each vector to determine the overall magnitude and direction of the resultant vector.

What is the direction of null vector?
There are two possible answers to this; a) It has no direction b) It points in all directions Answer a is really more true, as the notion of a null vector precludes any notion of a direction, but the correct answer is b.
Is it possible for flux to have a negative value?
Yes, it is possible for flux to have a negative value. This occurs when the magnetic field and the area vector are in opposite directions, leading to a negative flux value.
Is it possible for electric flux to have a negative value?
Yes, electric flux can have a negative value if the electric field and the area vector have opposite directions.
Explain how a swarm of flying insects can have a net momentum of zero?
If they fly in different directions, the momentum (which is a vector quantity) of the individual insects can cancel.If they fly in different directions, the momentum (which is a vector quantity) of the individual insects can cancel.If they fly in different directions, the momentum (which is a vector quantity) of the individual insects can cancel.If they fly in different directions, the momentum (which is a vector quantity) of the individual insects can cancel.
What the difference between vector and resultant vector?
Equilibrant vector is the opposite of resultant vector, they act in opposite directions to balance each other.
Is it possible to add a scalar to a vector?
It is not possible the addition of scalars as well as vectors because vector quantities are magnitude as well as direction and scalar quantities are the only magnitude; they have no directions at all. Addition is possible between scalar to scalar and vector to vector. Under some circumstances, you may be able to treat scalar quantities as being along some previously undefined dimension of a vector quantity, and add them that way. For example, you can treat time as a vector along the t-axis and add it to an xyz position vector in 3-space to come up with a four-dimensional spacetime vector.
Is it possible to add three vector of equal magnitude but different directions to get a null vector?
Consider an equilateral triangle. If each vector started at the center of the triangle and went through a different vertex than the other two vectors then they would cancel. I believe in order for them to add to a null vector they must be co-planer.
If the component of vector A along the direction of vector B is zero. What can you conclude about these two vectors?
Their directions are perpendicular.
Why vectors cannot be divided?
A vector is a combination of a value and a direction. While values can be divided, directions cannot. Simply no one ever defined a way to divide directions. You could make one up.
Can the directions of velocity and displacement of a particle be different?
Yes, the directions of velocity and displacement of a particle can be different. Velocity is a vector quantity that includes both speed and direction, while displacement is a vector quantity that represents the change in position.
