find the value of p given that this straight line is perpendicular to the vector i+2j+pkthe position vectors of the points K and L are given by OK=3i-2j+2k    and  OL=-i+j+3k

jishnudeepkar | Student

if ur talking about st line KL

then its vector will be OK - OL

2i - 3j - k

for perpendicular dot product = 0

2-6-p=0      or p=-4
