Answer:
(E) 1 or 2
Explanation:
Steady state error for unit step input is given by 
where 
is position error coefficient the value of is given by 
it will be only finite when the type of the open loop system will be 0 when the of the system will be 1 or 2 then 
becomes infinite and steady state error will become zero so the option (E) will be the correct answer
Answer: (C) 9.14 . 10⁻³ Ω
Explanation:
The resistance of a resistor, is proportional to his length and inversely proportional to his area, being the proportionality constant a property of the material, called resistivity.
The resistivity is defined as the inverse of the electrical conductivity, which depends on the number of charge carriers and the mobility of these carriers, which is different for each material.
So, we can calculate the resistance as follows:
R = 1/σ . L / A, where:
σ = electrical conductivity, l= length of the wire , A = wire cross-section (assumed circular).
Replacing by the values, we can calculate R as follows:
R = 1/6.1. 10⁷ (Ω.m) . 8.1 m. / π (0.0043)² m / 4 = 9.14 . 10⁻³ Ω
