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 NEET Exam Centres in Hyderabad 2024 Ecology & Environments NEET Exam Centres in Maharashtra 2024 CBSE Biotechnology and its Applications Class 12 Mind Map for Chapter 10 of Biology, Download PDF NEET Exam Centres in Tamil Nadu 2024 NEET Exam Centres in Karnataka 2024 Microbes in Human Welfare Class 12 Mind Map- Check Characteristics, Classification, Functions & Examples NEET Exam Centres in Gujarat 2024 Test your English Vocabulary CUET Exam Dates 2024 – Application Form, Fees, Eligibility
