Answer:
Magnitude of the resultant force will be 20N in the direction of
.
Step-by-step explanation:
It's given in the question that two forces have been applied on the object given.
Since force is a vector quantity, therefore, it has magnitude and direction both.
![F_1=20N](https://img.qammunity.org/2021/formulas/physics/high-school/84h19n8yc0zm58xriu56n4oozw9s8qj1d9.png)
![F_2=40N](https://img.qammunity.org/2021/formulas/physics/high-school/7y9p2k52v43mg30cej13on3acotk08bxn6.png)
Both the forces are in the opposite directions.
Therefore, magnitude of the resultant force of these forces will be,
![F_2-F_1=40-20](https://img.qammunity.org/2021/formulas/physics/high-school/1lr2mu7rstkemlzi3ieu1tran76u6vzm90.png)
= 20 N
And the direction of the resultant force will be towards
.
Therefore, magnitude of the resultant force will be 20N in the direction of
.
