Dear student,

We can write the vectors in terms of unit vectors as-

\vec{OA}=r\hat{i}
\vec{OB}=r\hat{j}
\vec{OC}=\dfrac{1}{\sqrt{2}}(\hat{i}+\hat{j})

Hence the resultant vector is(1+\dfrac{1}{\sqrt{2}})\hat{i}+(1+\dfrac{1}{\sqrt{2}})\hat{j}

Magnitude of the resultant=\sqrt{2}(1+\dfrac{1}{\sqrt{2}})=\sqrt{2}+1
