Answer:

So for an object moving in a circle, there must be an inward force acting upon it in order to cause its inward acceleration. This is sometimes referred to as the centripetal force requirement. The word centripetal (not to be confused with the F-word centrifugal) means center seeking.

Answer:

Force, F = 2356.19 N

Explanation:

Given that,

Diameter of the circular tip, d = 1 mm = 0.001 m

Its radius, r = 0.0005 m

Pressure created, $P=3\times 10^9\ N/m^2$

To find,

Force exerted on the nail.

Solution,

The pressure exerted by an object is equal to the force acting per unit area. Its formula is given by :

$P=\dfrac{F}{A}$

$F=P\times A$

$F=3\times 10^9\ N/m^2\times \pi (0.0005\ m)^2$

F = 2356.19 N

Therefore, the force exerted on the nail is 2356.19 N.
