Nonzero vectors →a,→b,→c satisfy →a.→b=0,(→b−→a).(→b – InterviewSolution

1.	Nonzero vectors →a,→b,→c satisfy →a.→b=0,(→b−→a).(→b+→c)=0 and 2\|→b+→c\|=\|→b−→a\|. If →a=μ→b+4→c then μ= ___
Answer» Nonzero vectors $\to a, \to b, \to c$ satisfy $\to a . \to b = 0, (\to b - \to a) . (\to b + \to c) = 0 a n d 2 \| \to b + \to c \| = \| \to b - \to a \|$ . If $\to a = μ \to b + 4 \to c t h e n μ =$ ___
