Question

If X and Y components of a vector
P
have numerical
values 3 and 4 respectively and that of P - Q have
numerical values 8 and 7 respectively, then the
magnitude of Q is consider all the vectors in first
quadrant)
​

Answer 1

Answer:

√34

Explanation:

P= 3i+4j.

P - Q=8i+7j

3i+4j - Q=8i+7j

3i-8i+4j-7j=Q

Q= -5i-3j

Q=√(-5)^2+(-3)^2

Q=√34

Answer 2

2/3 into 5 by 10 is very wrong very different
