Part 2 Calculated multiple choice questions Directions: Please choose the correct answer for the following 15 questions For the permittivity of free space use 8.85 pF/m for all questions An experiment in a certain gas to find Townsend's coefficients resulted in the curve shown in the fig. 2 where d is the distance between the plates, and I is the current. the field value was kept fixed throughout the experiment. Answer questions Q21 & Q22. Q. 21. If the labeled slope is 9/cm, the steady-state current is 0.6 nA at d-0.2 cm. The critical threshold distance for sustained discharge is 0.85 cm. Find the current when d-0.8 cm noting that at this distance the curve is out of the linear range. A. 326.42 NA B. 346.42 NA C. 366.42 nA D. 386.42 nA these parts Q. 22. If the critical threshold distance for sustained discharge is instead d=0.69 cm, the value of Townsend's second ionization coefficient is 0.101%, and the steady-state current is 0.58 nA when please solve d=0.45 cm. And if the current after increasing the distance is 0.95 nA, find the percentage of the supply voltage increment assume you are working in the linear range.
