Given \(\vec{B} = 3 \hat{i} - 5 \hat{j}\), what is the magnitude and angle of the vector?
  • Magnitude = \(\sqrt{3^2 + 5^2}\), Angle = \(\tan^{-1}(5/3)\)
  • Magnitude = \(\sqrt{3^2 - 5^2}\), Angle = \(\tan^{-1}(5/3)\)
  • Magnitude = \(\sqrt{3^2 - 5^2}\), Angle = \(\tan^{-1}(-5/3)\)
  • Magnitude = \(\sqrt{3^2 + (-5)^2}\), Angle = \(\tan^{-1}(-5/3)\)
