Question

the result of a 20 n force acting on an object to the right and a 30-n force acting on the object to the left is ____.
options:
a) 50 n
b) 10 n
c) 30 n to the right
d) 10 n to the left

Explanation:

Step1: Define the forces

Let the force to the right be \( F_{right}=20\ N \) (positive direction) and the force to the left be \( F_{left} = 30\ N \) (negative direction).

Step2: Calculate the resultant force

The formula for the resultant force \( F_{net}\) is \( F_{net}=F_{right}+F_{left}\).
Substitute the values: \( F_{net}=20+( - 30)\).
\( F_{net}=20 - 30=-10\ N\). The negative sign indicates the direction is to the left.

Answer:

10 N to the left
