Along cylindrical capacitor is made of a central wire of radius a = 2.50 mm surrounded by a conducting shell of radius b = 7.50 mm. the gap between the plates is filled with a dielectric of constant k = 3.68 and a potential difference of av = 120 v is applied across the plates. what is the capacitance per unit length c for this device? a) c = 1.86 x 10-10 f/m b) c = 5.06 x 10-11 f/m c) c = 8.34 x 10-11 f/m d) c = 3.07 x 10-10 f/m

The capacitance per unit length is

(b) is correct option.

Explanation:

Given that,

Radius a= 2.50 mm

Radius b=7.50 mm

Dielectric constant = 3.68

Potential difference = 120 V

We need to calculate charge per length for the capacitance

Using formula of charge per length

Put the value into the formula

We know that,

We need to calculate the capacitance per unit length

Using formula of capacitance per unit length

Hence, The capacitance per unit length is

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.

happy to

pls mark as brainliest.

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat
