So, the vectors P, Q and (P Q) are coplanar vectors Now (P X Q) is the cross product of vectors P and Q We know, cross product of two vectors generate a third vector which is perpendicular to the two vectors generating it through their vector product Thus, the vector (P X Q) must be perpendicular to the vectors P and Q, that is, perpendicular to the plane containing the vectors P and Q Now, the plane containing vectors P and Q, contain vector (P QPq = pcosθ qcosØIf we have any 2 vectors P and Q, the dot product of P and Q is given by P • Q = P Q cos θ where P and Q are the magnitudes of P and Q respectively, and θ is the angle between the 2 vectors The dot product of the vectors P and Q is also known as the scalar product since it always returns a scalar value
Suppose P and Q are two vectors If PQ = PQ than the angle between two vector is, CosX = (PQ) ×(PQ) /PQPQ CosX = 90°– Q²)/ (2 (P²Q²)) = (P²Answer is (b) Q = 0 If P Q = P Q Then Q = Q which is possible when Q = 0 (null vector)
