Question

which objects have no net force?
check all that apply!
a
b
c
d

Explanation:

Step1: Analyze object a

For object a, the vertical forces: \(25N\) (up) and \(25N\) (down) cancel each other (\(25 - 25=0\)). The horizontal forces: \(20N\) (left) and \(20N\) (right) cancel each other (\(20 - 20 = 0\)). Net force is \(0\).

Step2: Analyze object b

For object b, vertical forces: \(25N\) (up) and \(25N\) (down) cancel (\(25-25 = 0\)). Horizontal forces: \(15N\) (left) and \(20N\) (right). Net horizontal force \(F_{x}=20 - 15=5N
eq0\). Net force is not \(0\).

Step3: Analyze object c

For object c, vertical forces: \(25N\) (up) and \(25N\) (down) cancel (\(25 - 25=0\)). There are no horizontal forces. Net force is \(0\).

Step4: Analyze object d

For object d, vertical forces: \(25N\) (up) and \(25N\) (down) cancel (\(25 - 25 = 0\)). Horizontal force: \(20N\) (right) with no opposing horizontal force. Net force is \(20N
eq0\).

Answer:

A. Object a, C. Object c
