Answer:
10N to the left side towards you
Explanation:
The net force is the resultant force that acts on a body.
Force is a push or pull on a body. Â Â
 Push to left side  = 25N
 Pull to the right  = 15N
Net force  = Push to left side  -  Pull to the right  = 25N  - 15N
 Net force  = 10N to the left side towards you
The net force is therefore 10N to the left side towards you
