If A represents a vector two units in length directed due west, B represents a vector three units in length directed due north a
Ludmilka [50]

Answer:

Step-by-step explanation:

Given

Vector A has two units in length due to west i.e.

\vec{A}=-2\hat{i}

Vector B has one unit in length due to North i.e.

\vec{B}=\hat{j}

Also A+B=C-D

i.e. C-D=-2\hat{i}+\hat{j}--------1

also 2B-A=C+D

i.e. C+D=2\times \hat{j}+2\hat{i}------2

From 1 and 2

2C=3\hat{j}

C=1.5\hat{j}

D=2\hat{i}+0.5\hat{j}
