Answer 2

Answer:

The projection of the vector B on the vector on R​ is 3.2.

Step-by-step explanation:

It is given that the two vectors are perpendicular to each other.

Assuming, A=3i and B=4j

R is the resultant vector.

∴R=3i+4j

The projection of B on R can be calculated using,

$\frac{RB}{R} =\frac{[3i+4j]4j}{\sqrt{3^{2}+4^{2} } }$

=16/5

=3.2

Therefore, the projection of the vector B on the vector on R​ is 3.2.
