Problem 12PE

The pressure exerted by a phonograph needle on a record is surprisingly large. If the equivalent of 1.00 g is supported by a needle, the tip of which is a circle 0.200 mm in radius, what pressure is exerted on the record in N/m2 ?

Step-by-Step Solution:

Solution to 12PE

Step 1 of 3</p>

We need to calculate the pressure exerted by the tip of the phonograph needle on the record.

Given,

Mass of the needle, Radius of the tip of the needle, Step 2 of 3</p>

The pressure exerted by a perpendicular force acting on a cross-sectional area is, Area of the tip of the needle,   Force acting on the vinyl record is the force due to gravity on the needle thus,   Step 3 of 3
