A vector quantity is a physical quantity having magnitude and direction both. For e.g. velocity is a vector quantity and in physics it is velocity is generally denoted as:
v (bar) = 2i+3j+4k
where in general,
i=velocity in x-direction
j=velocity in y-direction
k=velocity in z-direction
2,3 and 4 are magnitudes respective to their directions.

What is the magnitude of a vector 3V?
3 times the magnitude of the vector V - which is not known.3 times the magnitude of the vector V - which is not known.3 times the magnitude of the vector V - which is not known.3 times the magnitude of the vector V - which is not known.
The magnitude of a vector represents its?
That depends on what the vector, itself, represents. For example, if the vector represents velocity, then the magnitude of the vector represents speed. If the vector represents displacement, then the magnitude of the vector represents distance.
Can a vector have a component greater than the magnitude of vector?
no a vector cannot have a component greater than the magnitude of vector
What is different between negative vector and null vector?
A null vector has no magnitude, a negative vector does have a magnitude but it is in the direction opposite to that of the reference vector.
A direction a vector is drawn indicates the magnitude of the vector?
No. The size of the size of the vector drawn indicates the magnitude.
