Explanation Given: The density of silicon, ρ = 2300 kg/m 3 The initial frequency of cantilever, f o = 12 MHz The decrease in frequency, Δ f = − 50 Hz A cantilever of mass ( m ) can be modeled as a block of mass ( 1 3 m ) . The dimension of the cantilever, 4000 nm × 400 nm × 100 nm Formula Used: Density: ρ = M V Here, M is the mass and V is the volume. f = 1 2 π k m f = 1 2 π k m d f = 1 2 π ( − 1 2 ) k m − 3 / 2 d m d m = − 2 m d f f Calculation: Volume: V = 4000

Simple harmonic motion

Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards…

Simple Pendulum

A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.

Oscillation

In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion tak…
