Questions
If vectors are functions of time, then the value of t at which they are orthogonal to each other is:
detailed solution
Correct option is D
A→ = cosωti^+sinωt j^B→ = cos(ωt2)i^+sinωt2 j^For A→ and B→ orthogonal A.→B→ = 0cosωt i^+sinωt j^.cosωt2i^+sinωt2j^ = 0cosωt.cosωt2+sinωt.sinωt2 = 0cos(ωt-ωt2) =0⇒ cosωt2 = 0ωt2 = π2 ⇒ ωt = π ⇒ t = πωTalk to our academic expert!
