Potential difference is the difference in electrical potential. when the lowest potential is taken to be at zero volts then the potential 1.00 cm from that plate is 750 V.

What is the potential difference?

A potential difference is defined as the difference in the electrical potential between two points.

Given to us

Distance between the plate, d = 4 cm = 0.04 m

Electric field, E = 7.50×104 V/m .

A.) We know that for two parallel conducting plates, the potential difference between the plate is given as,

$\triangle V = Ed$

E = Magnitude of the electric field

d = distance between the plates

Substitute the values,

$E = 7.5 \times 10^4 \times 0.04\\\\E = 3000\rm\ V$

B.) We already know the potential difference between the two plates, therefore,

The potential difference between the two plates,

$\triangle V= V_A - V_B$

Since, one of the plates is having zero potential, therefore,

$\triangle V= V_A = 3000\rm\ V$

We know that the potential difference between the two plates is 300 which are 4 cm apart, therefore,

$\dfrac{\triangle V}{d} = \dfrac{V}{1}\\\\V = 750 \rm\ V$

Hence, when the lowest potential is taken to be at zero volts then the potential 1.00 cm from that plate is 750 V.

(a) 3000 V

For two parallel conducting plates, the potential difference between the plates is given by:

$\Delta V=Ed$

where

E is the magnitude of the electric field

d is the separation between the plates

Here we have:

$E=7.50\cdot 10^4 V/m$ is the electric field

d = 4.00 cm = 0.04 m is the distance between the plates

Substituting,

$\Delta V=(7.50\cdot 10^4 V/m)(0.04 m)=3000 V$

(b) 750 V

The potential difference between the two plates A and B is

$\Delta V = V_B - V_A = 3000 V$

Let's take plate A as the plate at 0 volts:

V_A = 0 V

The potential increases linearly going from plate A (0 V) to plate B (3000 V).

So, if the potential difference between A and B, separated by 4 cm, is 3000 V, then the potential difference between A and a point located at 1 cm from A is given by the proportion:

3000 V : 4 cm = V(1 cm) : 1 cm

and solving for V(1 cm) we find:

$V(1 cm)=\frac{(3000 V)(1 cm)}{4 cm}=750 V$

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

Avehicle has an oil leak that is causing the entire oil pan to be wet, but inspection reveals no exact source after cleaning off the oil residue. technician a says to install a fluorescent dye in the crankcase and operate the engine, then re-inspect for leaks with a special light (black light). technician b says the oil leak may be coming from a source at the top of the engine, such as a valve cover gasket. who is correct?
