Let →a,→b,→c are vectors such that |→a|=1,|→b|=6,|→c|=2√3 and (→a+2→b) is perpendicular to →c,(→b+2→c) is perpendicular to →a and (→c+2→a) is perpendicular to →b. Then the value of |→a+→b+→c|=

Answer» Let a,b,c are vectors such that |a|=1,|b|=6,|c|=23 and (a+2b) is perpendicular to c,(b+2c) is perpendicular to a and (c+2a) is perpendicular to b. Then the value of |a+b+c|=
