If vector PPP = 5.2î - 2.9ĵ + 1.8k̂ and vector QQQ = 6.7î + 3.4ĵ - 2.1k̂. Find i) their cross-product, ii) the angle between the two vectors.
i. P×QP\times QP×Q = -0.03î + 23.0ĵ +37.1k̂, ii. θ = 59°
i. P×QP\times QP×Q = 0.03î - 23.0ĵ -37.1k̂, ii. θ = 59°
i. P×QP\times QP×Q = -0.03î + 23.0ĵ +37.1k̂, ii. θ = 64°
i. P×QP\times QP×Q = 0.03î - 23.0ĵ -37.1k̂, ii. θ = 64°
