Question

Let a → = 2 i ^ - j ^ + 3 k ^ , b → = i ^ + j ^ - 4 k ^ and non-zero vector c → are such that a → × b → × c → = a → × b → × c → , then vector c → may be, 4 i ^ - 2 j ^ + 6 k ^, 4 i ^ + 2 j ^ + 6 k ^, i ^ + j ^ - k ^, i ^ - 4 j ^ + k ^

MARKS App · Accepted Answer

a → × b → × c → = a → × b → × c → a → ⋅ c → b → − b → ⋅ c → a → = a → ⋅ c → b → − a → ⋅ b → c → ⇒ c → must be parallel to a →
