If P Q=Q P, the angle between P and Q is (0^ < <360^ ). The value of ' ' will be

Correct answer: 180. (180) If P Q=Q P Only if P=0 Or Q=0 The angle b/w P \&Q is (0^ < <360^ ) So =180^

JEE Previous Year Question

$If P \times Q = Q \times P, the angle between P and Q is θ (0^{\circ} < θ < 360^{\circ}) . The value of ' θ' will be$

Topic: JEE PYQ

Answer: 180. Full step-by-step solution below.

Correct answer: 180

(180) If P \times Q = Q \times P Only if P = 0 Or Q = 0 The angle b/w P & Q is θ (0^{\circ} < θ < 360^{\circ}) So θ = 180^{\circ}
