Grade 12Modern PhysicsPlz answer it as soon as possible I just didnt get the point how to take the vectors Nikhil 7 Years agoGrade 12
Arun7 Years agoDear Nikhil a vector in plane of b and c = tb + sc = (t + s) i + (2t + s) j + ( – t – 2s) k now its projection on a = 2 t + 2s – 2t – s – t – 2s / sqrt (6) = sqrt (2/3) now solve for t and s.then you can check options
