Answer:A

=  

i

^

Acosθ+  

j

^

​  

Asinθ and consider  

A

=  

i

^

x+  

j

^

​  

y. Now, B is normal to A then:  

A

.  

B

=0  

A

.  

B

 =(  

i

^

Acosθ+  

j

^

​  

Asinθ).(  

i

^

x+  

j

​  

y)

       =Axcosθ+Aysinθ

Therefore, for  

A

.  

B

=0  x should be of form Bsinθ and y of form −Bcosθ.
