Question

Problem 1

Answer 1

Given information

We have given that the diameter of round plates of a capacitor, is 8.0 cm, and plates are 1.1 mm apart. We have also given that the voltage across the plates is changing at a rate of 120 V/s.

Step-by-step explanation

Step 1.

The electric field E between the plates is 

 

Here E is electric field, V is potential difference and d is distance between plates.

So the formula for the rate of change of electric field is 

 

 

Before substituting the values we will convert distance in meter, so the distance is 0.0011m.
