Find the sum of the following vectors A=3i-12j and B=4i+7j

(I). The sum of the vectors is (7i-5j).

(II). The sum of the vectors is (8i+7j).

Explanation:

Given that,

(I). Vector A

Vector B

Suppose, (II). Vector A

Vector B

(I). We need to calculate the sum of the vectors

Using formula of sum

Where,

(II). We need to calculate the sum of the vectors

Using formula of sum

Put the value into the formula

Hence, The sum of the vectors is (7i-5j).

The sum of the vectors is (8i+7j).
