Let P , Q and R be three non-zero vectors in the three dimensional right handed rectangular coordinate system. Then

Options

  1. Aif P , Q and P + Q are unit vectors then | P - Q |= 3 2 .
  2. Bthe vectors P ( Q R ), Q ( R P ) and R ( P Q ) are coplanar.
  3. Cif P Q = R and Q R = P then P , Q and R are orthogonal in pairs and | P |=| R |
