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

Short Answer

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