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 = $$\tan^{-1}(-5/3)$$
