the potential at the center of curvature of the arc = v = Q ∕ (4πε∘a) or
ATQ,
We have density of charge,
λ =
Where L is the rod's length, in this case the semicircle's length L = πr
Q is the charge on the rod
The potential created at the center by an differential element of charge is:
where k is the coulomb's constant
r is the distance from dQ to center of the circle
v = ∫ , Where a = radius, k = 1 / 4πε∘
v = or Q ∕ (4πε∘a)

Answer:
e) None of these is true
Explanation:
Given that
Temperature = 0 K
We know that relationship between kelvin and Farenheit scale
Now by putting the values
So F= - 459.67°F
So we can say that 0 K is equal to - 459.67°F.
So the our option e is correct.
