What is the resultant of the two vectors shown?

Option C

Explanation:

As we know by the vector addition rule when two vectors are added such that if they are added head to tail then the resultant or the addition of two vectors will be represented by another vector which will be represented by third side of triangle in reverse order that is from tail to head.

This above rule is known as triangular law of addition in which two vectors are represented by two two adjacent sides of a triangle and the third side will be taken as the resultant.

So here two given vectors are one is towards right then next is downwards so we will join them tail to head and then the resultant of two vectors will be given by third side which is in reverse order which is tail to head

so here correct answer will be

OPTION C

a and b sometimes have a positive value
