When we apply a muscular force with a hammer, which other force fixes the nail in the wall?

Correct option is B

The correct answer is (b) Friction.
· When a nail is driven into a wall with a hammer, the primary force fixing the nail in place is friction.
· As the nail penetrates the wall, the material of the wall exerts a normal force perpendicular to the surface of the nail. This results in a frictional force that resists the motion of the nail.
· The friction between the nail and the wall material helps to hold the nail in place, preventing it from easily being pulled out.
Information Booster:
Magnetic force:
· Magnetic force involves attraction or repulsion between objects due to their magnetic fields. It is not involved in fixing a nail in the wall.
Electrostatic force:
· Electrostatic force is the force between charged particles. It is also not relevant in the context of fixing a nail in the wall.
Spring force:
· Spring force is the force exerted by a compressed or stretched spring upon any object attached to it. It is not involved in the process of fixing a nail in a wall.
