Q1010^(8)Pa. The wire diameter is 25\mu m, length 3 cm . Pressure sensitivity of wire material is 25\times 10^(-12)Pa^(-1). Resistivity 45\times 10^(-6)\Omega cm. Find the change in resistance due to maximum pressure.
{(:(0.1)/(100)=2.3\times 10^(-11)\times \Delta P):}
Change in pressure, \Delta P is given by, 1\times (10^(-3))/(2.3)\times 10^(-11)=43.47\times 10^(6)(N)/(m^(2))
