Why must the electric field be normal to the surface at every point of a charged conductor?

Physics
1 answer:
solong [7]3 years ago

-- If the field were inclined to the surface, then it would have
some component parallel to the surface. 

-- Then, since we're talking about a conductor, the charges
on the object would move in response to that component
of the field, until there was no longer any component of the
field trying to move them.

Urgent!!!!!! 20 points!!!!!!<br> how are the speed, wavelength and frequency of a wave related
zheka24 [161]

Answer:

The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength. Speed shows how long it takes for wavelengths to travel.

PLEASEEEEE!!!!
Fudgin [204]

Answer:

<h3>The answer is 2.0 g/mL</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 100 g

volume = 50 mL

We have

density =  \frac{100}{50}  =  \frac{10}{5}  \\

We have the final answer as

<h3>2.0 g/mL</h3>

Hope this helps you

After dinner, Joanne did not put the leftover casserole away until after watching her favorite television show. What is the long
Sever21 [200]

Answer:

At most 2 hours

Explanation:

According to my research of various health departments it is said that cooked food should not be left out in room temperature for more than 2 hours, assuming that room temperature is between 40°F and 140°F. This is because after 2 hours bacteria starts to grow at an increased rate and can have various health effects on the person consuming the food. Therefore food is best wrapped and placed in the refrigerator.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
