The image produced is magnified and real.
maximum static friction acting on the object will be

plug in all values

So here it means that if applied force is less than or equal to 58.8 N then the object will remain stationary as friction can balance the external force upto this limit of external force
So here it is given that applied force is 20 N
so here object will not move due to this force and it will remain at rest always
due to this applied force
If the car is on the moon, its mass is about 817 kg.
If it's on the Earth, its mass is about 135 kg.
Reduce friction because friction just makes things harder
