Solution:Given, projection of b¯ on a→=a→·b→|a→|=|a→|⇒ b1+b2+24=4⇒b1+b2=2Also, (a→+b→)⊥c→⇒(a→+b→)·c→=0⇒1+b15+1+b21+22(2)=0⇒ 5b1+b2=-10Solving (i) and (ii), we get b1=-3 and b2=5Now, |b→|=b12+b22+2=6 Related content Oppositional Defiant Disorders Good Friday Wishes CBSE Class 9 Physics Motion Worksheet Autism Spectrum Disorder Sine and Cosine Waves Hindu Festivals List 2024 JEE Main Eligibility Criteria 2024 Session 2 (Released), Age Limits, Qualifying Marks, and Important Factor MCQs on Plant Hormones Class 10 5 Reasons To Choose The Commerce Stream After 10th Fl Words
