Question

1. net force: n forces are: balanced unbalanced object will: not accelerate accelerate

Explanation:

Step1: Define direction of forces

Let the right - hand direction be positive and the left - hand direction be negative. The forces acting on the object are $F_1 = 200\ N+75\ N$ (right - hand side) and $F_2=- 210\ N$ (left - hand side).

Step2: Calculate net force

The net force $F_{net}$ is calculated by adding all the forces together. $F_{net}=(200 + 75)-210$. First, $200+75 = 275\ N$, then $F_{net}=275 - 210=65\ N$.

Step3: Determine force balance

Since $F_{net}=65\ N
eq0\ N$, the forces are unbalanced.

Step4: Determine object's motion

According to Newton's second law ($F = ma$), when there is a non - zero net force acting on an object, the object will accelerate.

Answer:

Net force: $65\ N$
Forces are: unbalanced
Object will: accelerate
