# Let → a = 3 → I + 4 → J . Write a Vector → B Such that → a ≠ → B , but a = B. - Physics

Sum

Let $\vec{A} = 3 \vec{i} + 4 \vec{j}$. Write a vector $\vec{B}$ such that $\vec{A} \neq \vec{B}$, but A = B.

#### Solution

A vector $\vec{B}$ such that  $\vec{A} \neq \vec{B}$, but A = B are as follows:

$(i) \ \vec{ B} = 3 \vec{i} - 4 \vec{j}$

$(ii) \ \vec{ B} = 3 \vec{j} + 4 \vec{k}$

$(iii) \ \vec{ B} = 3 \vec{k} + 4 \vec{i}$

$(iv) \ \vec{ B} = 3 \vec{j} - 4 \vec{k}$
