Question

determine the net force
a 17 n right
b 3 n left
c 3 n right
d 0

Explanation:

Step1: Analyze the direction of forces

The forces are in opposite directions. Let the right - direction force be positive ($F_1 = 10N$) and the left - direction force be negative ($F_2=-7N$).

Step2: Calculate the net force

The net force formula is $F_{net}=F_1 + F_2$. Substitute the values: $F_{net}=10N+( - 7N)$.
$$F_{net}=10N - 7N=3N$$
Since the result is positive, the direction is to the right.

Answer:

C. 3 N Right
