To calculate:The unit vector in the opposite direction of
Answer to Problem 68RE
The value of the vectorsis:
Explanation of Solution
Given information:
The vectors:
Formula used:
The unit vector
To find the unit vector in the direction of opposite to the given vector multiply the unit vector by
Calculation:
Consider the vectors:
Put the value of the vectors to find the unit vector
Now
Now write the vectors
To write the vectors
Apply the formula here to find the direction vector
As from above:
Then,
Now to find the opposite direction of unit vector multiply the unit vector by
The unit vector in the opposite direction of the vector,
Thus, the value of the magnitude of vectors are
