solved example 2: Answer: B Explanation: Two vectors with different magnitude and same direction are not always collinear. b/c The given vectors may not be proportional. Eg. A= 2i+3j and B= 4i+9j
Solved Example 8. Answer B nw. choice A) |A+B|=|A-B|^2 በዚህ አስተካክሉት power point ላይ |A+B|=|A-B| ብቻ ነው ያለው።
