Question

Two force vectors point in opposite directions. If their magnitudes are 3.53 newtons and 7.29 newtons, then what is the magnitude of their sum?

Answer 1

Answer:

3.76 N

Explanation:

We are given that two force vectors point in opposite directions.

Let

$\mid F_1\mid=7.29N$

$\mid F_2\mid=-3.53$

Because second force act in opposite direction.

We have to find the magnitude of sum of two forces.

We know that triangle law of addition

Resultant sum=$\mid F_1\mid+\mid F_2\mid$

Substitute the values then we get

Resultant sum of two forces=$7.29-3.53$

Resultant sum of two forces=3.76 N

Hence, the magnitude of sum of two forces=3.76 N
