Physics - Vectors Question with Solution | TestHub

Two vectors$\overrightarrow{P}$and$\overrightarrow{Q}$have equal magnitudes. If the magnitude of$\overrightarrow{P}+\overrightarrow{Q}$is$n$times the magnitude of$\overrightarrow{P}-\overrightarrow{Q},$then angle between$\overrightarrow{P}$and$\overrightarrow{Q}$is
