Two vectors

\overrightarrow A

and

\overrightarrow B

have equal magnitudes. If magnitude of

\overrightarrow A

+

\overrightarrow B

is equal to two times the magnitude of

\overrightarrow A -\overrightarrow B

, then the angle between

\overrightarrow A

and

\overrightarrow B

will be :

A
${\sin ^{ - 1}}\left( {{3 \over 5}} \right)$
B
${\sin ^{ - 1}}\left( {{1 \over 3}} \right)$
C
${\cos ^{ - 1}}\left( {{3 \over 5}} \right)$
D
${\cos ^{ - 1}}\left( {{1 \over 3}} \right)$
