Question

If a → and b → are two non-collinear vectors, then a → × b → × a → a → 2 represent, a vector perpendicular to the plane of a → , b →, projection of b → along a vector perpendicular to the vector a →, projection of a → along the vector perpendicular to b →, a vector on the plane of a → , b → whose magnitude is equal to a → + b →

MARKS App · Accepted Answer

a → × b → × a → a → 2 = a → · a → b → - a → · b → a → a → 2 = b → - a → · b → a → a → 2 = b → - a → · b → a → × a → a → = projection of b → along a vector ⊥ to the a → .
