Answer:
3.76 N
Explanation:
We are given that two force vectors point in opposite directions.
Let
[tex]\mid F_1\mid=7.29N[/tex]
[tex]\mid F_2\mid=-3.53[/tex]
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=[tex]\mid F_1\mid+\mid F_2\mid[/tex]
Substitute the values then we get
Resultant sum of two forces=[tex]7.29-3.53[/tex]
Resultant sum of two forces=3.76 N
Hence, the magnitude of sum of two forces=3.76 N
