Question

A is a vector which when added to the resultant of vectors (2î - 3j + 4k) and (i + 5j + 2k). yields a unit
vector along the y-axis. Then vector Ā is :....??​

Answer 1

Answer:

Let, B=(2i−3j+4k) and C=(i+5j+2k)

As per the question given:

A+B+C=1j

∴A+(2i−3j+4k)+(i+5j+2k)=1j

∴A=−3i−j−6k
