If vector A = 6i - 8j then 4A magnitude has
Answers
QUESTION:
The correct question should be:
If vector A = 6i - 8j then vector 4A has a magnitude ____?
ANSWER:
For the given vector A, the magnitude of vector 4A will be 40 units.
Given,
Vector A = 6i - 8j.
To find,
The magnitude of vector 4A.
Solution,
Here, the given vector is,
Let there be a vector P, such that,
Then the magnitude of vector P is given by
For the given vector A, we have to find the magnitude of vector 4A, so first, we should find the vector 4A by multiplying the given vector A by 4.
This can be done as follows.
Now, the magnitude of 4A will be,
Therefore, for the given vector A, the magnitude of vector 4A will be 40 units.
Answer:
The Magnitude=40 units
Explanation:
granted,
Vector A = 6i - 8j.
Fine,
Vector size 4A.
Solution,
Here is the given vector,
A=6i-8j
Let there exist a vector P, so
P=xi+yj
Then the size of the vector P is given by the relation
For a given vector A we need to find the size of the vector 4A, so first we have to find the vector 4A by multiplying the given vector A by 4.
It can be as follows.
A=6i-8j
4A=4(6i-8j)
4A=24i-32j
Now the size can be 4A,
4A=
=
==40
Therefore, for a given vector A, the size of vector 4A would be 40 units.
