Step-by-step explanation:
Explanation:
Given: A= 4i - 3j , B = 6i - 5j .
To find: The vector having magnitude 7 parallel to B - A is ?
Solution:
Step 1: Find B-A
B-A = 6i-5j-4i+3j
B-A = 2i-2j
Step 2: The vector parallel to B-A is =k(2i-2j).
Put the value of k so that the magnitude of vector is 7.
k should be 7/2√2
Thus, the vector which is parallel to B-A is
Verification:
If a vector is xi+yj then it's Magnitude is
Thus,
Here
Magnitude:
Final answer:
or
