$v = 2\hat{i} + 3\hat{j} + \hat{k}$ ની દિશામાં $\sqrt{7}$ માન ધરાવતો સદિશ કયો છે?

• A
  $\frac{2}{\sqrt{3}}\hat{i} + \frac{3}{\sqrt{3}}\hat{j} + \frac{1}{\sqrt{3}}\hat{k}$
• B
  $\hat{i} + \frac{3}{2}\hat{j} + \frac{1}{2}\hat{k}$
• C
  $\frac{2}{\sqrt{2}}\hat{i} + \frac{3}{\sqrt{2}}\hat{j} + \frac{1}{\sqrt{2}}\hat{k}$
• D
  $\frac{2\sqrt{7}}{\sqrt{14}}\hat{i} + \frac{3\sqrt{7}}{\sqrt{14}}\hat{j} + \frac{\sqrt{7}}{\sqrt{14}}\hat{k}$
