A vertical plate 3m wide and 2m high is cooled in a large water tank; its temperature is 90.

A vertical plate 3m wide and 2m high is cooled in a large water tank; its temperature is 90. The average water temperature is 40. Find the heat transferred to the water

So, in order to solve this problem, we need a special formula.

It looks like this:

E = k * q / r / r.

Despite the very strange appearance, she will help us very seriously.

q is the charge in this formula.

r – in this formula, the distance to this very charge.

Now all that remains for us to do is substitute the data into the formula and calculate the answer to the problem.

E = 20 * 10-6 * 9 * 10 ^ 9 / 0.02 / 0.02.

We consider, and the following is obtained.

450 * 10 ^ 6 V / m.

This will be the correct answer to the problem.
