Two plates of area 30.0 cm^2 are separated by a distance of 0.0590 cm. If a charge separation of 0.0240 μC is placed on the two

Answer:

V=533.33 V

Explanation:

Given that

A= 30 cm²

d= 0.059 cm

Q= 0.0240 μ C

We know that capacitance given as

$C=\dfrac{\varepsilon _oA}{d}$

Now by putting the values

$C=\dfrac{8.85\times 10^{-12}\times 30\times 10^{-4}}{0.059\times 10^{-2}}$

$C=4.5\times 10^{-11}\ F$

Voltage difference given as

Q= V .C

V=Q/C

$V=\dfrac{0.0240\times 10^{-6}} {4.5\times 10^{-11}}$

V=533.33 V
