Question

True-False vector Which of the following statements is correct/incorrect? If (a dot b) = 0 then a = 0 or b = 0. If a x b = 0 then a = 0 or b = 0. a dot (b x a) = 0 for all vectors a and b. The sum of the magnitudes of two vectors can be equal to the magnitude of the sum of these two vectors. The scalar product can be a negative quantity. If (a dot b)-(a dot c) then b-c. If three non-zero vectors add up to zero then they must all be in the same plane Submit Answer You have entered that answer before Incorrect. Tries 21/30 Previous Tries
