Question

6.Nails have pointed ends. This results in a *
decrease in the force exerted on them.
a decrease in the effect of the force exerted on them.
an increase in the force exerted on them.
an increase in the effect of the force exerted on them.​

Answer 1

Answer :-

• Nails have pointed ends. This results in an increase in the effect of the force exerted on them.

Hence, Option D is correct answer

Explanation:-

• As we know that,

Pressure = F / A

• F denotes the force exerted on the body

• A denotes the area on the which the force is exerted or it results.

Pressure is defined as the force per unit area.

• The nails have pointed ends because it covers minimize area and result into more pressure.

• So when we hit the nails head it means the force that we exerted on nail is converted into large pressure due to the small area of the tail and the nail is gone inside the wall.

Hence, It satisfy the above statement that if the nails have pointed ends then it results into an increase in the effect of the force exerted on them $.$
