Q3 of 25 Page 10

For what value of ‘x’ are the vectors and perpendicular to each other.

Given: and


To find: the value of x


Formula used:


If two vectors are perpendicular, their dot product is zero


Hence,



Therefore,





⇒ 2 – 2x + 3 = 0


⇒ - 2x + 5 = 0


⇒ - 2x = –5



Hence, the value of x is
