Two parallel conducting plates are connected to a constant voltage source. The magnitude of the electric field between the plates is 2388 N/C. If the voltage is tripled and the distance between the plates is reduced to 1 5 the original distance, what is the magnitude of the new electric field

Respuesta :

Answer:

The magnitude of the new electric field is 35820 N/C.

Explanation:

Given:

Original magnitude of electric field (E₀) = 2388 N/C

Original voltage = 'V' (Assume)

Original separation between the plates = 'd' (Assume)

Now, new voltage is three times original voltage. So, [tex]V_n=3V[/tex]

New distance is 1/5 the original distance. So, [tex]d_n=\dfrac{d}{5}[/tex]

Now, electric field between the parallel plates originally is given as:

[tex]E_0=\frac{V}{d}=2388\ N/C[/tex]

Let us find the new electric field based on the above formula.

[tex]E_n=\frac{V_n}{d_n}\\\\E_n=\frac{3V}{\frac{d}{5}}\\\\E_n=15(\frac{V}{d})[/tex]

Now, [tex]\frac{V}{d}=2388\ N/C[/tex]. So,

[tex]E_n=15\times 2388=35820\ N/C[/tex]

Therefore, the magnitude of the new electric field is 35820 N/C.
