Answer:
P = 795.77 Mpa
Explanation:
Given that,
Force exerted by the hammer, F = 10⁴ N
The nail can be considered as a circle with radius of
We need to find the pressure exerted on the wall. Pressure is equal to force acting per unit area. So
We know that, 1 MPa = 1000000 Pa
So, P = 795.77 Mpa
So, the pressure exerted on the wall is 795.77 Mpa.
