The Figure Shows Two Vectors $\overrightarrow { \mathbf { B } }$

Short Answer

The figure shows two vectors $\overrightarrow { \mathbf { B } }$ and $\overrightarrow { \mathrm { C } }$ , along with their magnitudes and directions. The vector $\vec { D }$ is given by $\vec { D }$ = $\overrightarrow { \mathbf { B } }$ - $\overrightarrow { \mathrm { C } }$ . (a) What is the magnitude of vector $\vec { D }$ ?
(b) What angle does vector $\vec { D }$ make with the +x-axis?
