Question

stack a with minus on top comma stack b with minus on top comma stack c with minus on top are non-coplanar vectors and stack a with minus on top plus stack b with minus on top plus stack c with minus on top and stack b with minus on top plus stack c with minus on top plus stack d with minus on top are collinear with stack d with minus on top and stack a with minus on top respectively then stack a with minus on top plus stack b with minus on top plus stack c with minus on top plus stack d with minus on top is

  1. t stack a with ‾ on top,where t is scalar    
  2. s stack d with ‾ on top, where s is a scalar    
  3. p left parenthesis stack a with ‾ on top plus stack d with ‾ on top right parenthesis, where p is a scalar
