Answer 2

let's are the requested vector

r = ai + bj + ck

now given that

r and you are prependicular

therefore

r ,q is = 9

(ai+ bj +ck ). (i–2j+k)=0

a*1+b*(–2)+cx1=0

a–2b+c=0........(1)

also given that

r is coplanar with the vector p and q

therefore

P Q R =0

finding P q r

PQR = 1 1 1

1 –2 1

a b c

=1 [–2c–b]–1[c–a]+1[b+2a]

= –2c –b–c + a+ b + 2a

–3c+3a

this answer is right

please give me a follow and thanks and star
