If $\vec{A} = \hat{i} A \cos \theta + \hat{j} A \sin \theta$ is a vector,then another vector $\vec{B}$ which is perpendicular to $\vec{A}$ is given by:

• A
  $\hat{i} B \cos \theta + \hat{j} B \sin \theta$
• B
  $\hat{i} B \sin \theta + \hat{j} B \cos \theta$
• C
  $\hat{i} B \sin \theta - \hat{j} B \cos \theta$
• D
  $\hat{i} A \cos \theta - \hat{j} A \sin \theta$
