Question:7
What is the projection of on ?
View Solution
Angle O between two vectors is given by:
Here,
a, = l,bl
Thus,
or, 900
The two vectors are perpendicular to each other.
Hence, the projection Of on is zero.
Here, a, b and c are coefficients of i cap, j cap and k cap.

Mamta Sharma answered this
a1 is the coefficient of i cap of 2- j cap, that is 1.
b1 is coefficient of j cap that is - 1.
c1 is coefficient of k cap that is 1.
Similarly for, 2+j cap,
a1=1
b1=1
and c1=1
