Explanation:

The vector product of two vectors

A

and

B

is defined by

A

×

B

=

n

^

∣A∣∣B∣sinx, where

n

^

is the unit vector perpendicular to both A and B vectors and x is the angle between them.

Here in this question the vector product of

P1

and

P2

vectors is zero. This is only possible in two cases: 1) Any of the vectors is zero itself or 2) the sin of the angle between them is zero.

From the given options, the vector parallel to the given vector

i

^

is −4

i

^
