Answer:
x=0.53
Explanation:
Using Gauss law the field is uniform so
E=ζ/ε
Charge densities ⇒ζ=1.
ε=8.85
Force of charge is
So finally knowing the acceleration and the time the distance can be find using equation of uniform motion
Answer:
Option B
Change in entropy of the process is
Explanation:
The entropy of a system is a measure of the degree of disorderliness of the system.
The entropy of a system moving from process 1 to 2 is given as
recall from first law,
hence we have,
since the process is isothermal,
this gives us
integrating within the limits of 1 and 2, will give us
also from ideal gas laws,
hence we have
This makes the correct option B
