Answer:
ΔE / E = ΔV / V + Δd / d
Explanation:
The electric field and voltage are related by the expression
E = V / d
The uncertainty of the field is
ΔE / E = ΔV / V + Δd / d
We see that the uncertainty of the field must be added the uncertainty of the distance that in the measure of the different potential has no effect.
The only case in which the uncertainties are equal is if the distance measurement has no uncertainty, or the separation of very high
Answer:
The self-inductance is 
Explanation:
From the question we are told that
The number of loops is 
The length of the rod is 
The radius of the rod is 
The self-inductance for the solenoid is mathematically represented as

Now the cross-sectional of the solenoid is mathematically evaluated as

substituting values


and
is the permeability of free space with a value 
substituting values into above equation
