Question

An accelerometer has a seismic mass of 0.05 kg and a spring constant of $3\times {10}^{3}N/m.$ The maximum permissible displacement of the mass is $\pm 1mm.$ The maximum measurable acceleration in $m/s^2$ is

• A. 60

Answer 1

The correct option is A 60
$\text{Acceleration (a)}=\frac{Kx}{M}$

$K=3\times {10}^{3}N/m$

$M=0.05kg$

$x=\pm 1mm$

$a=\frac{3\times {10}^3\times 1\times {10}^{-3}}{0.05}=60m/s^2$
