写真見づらくてすみません。 2021年九州工業大学後期の物理の問題です。 (8)の解き方を教えていただけるとありがたいです

物理2 中心軸 [1] 小さな穴をあけた薄い導体板1,2が、真空中に図1のように距離dだけ離して 平行に置かれている。導体板1は、導体板2より電位がVだけ高く,導体板の 板面は鉛直方向に平行である。今,質量mで正の電気量Qをもつ荷電粒子を 図1の左側から導体板1の穴の中心に速さ で導体板に垂直に入射させた。鉛 直上向きにz 軸を取り,清体板1の穴の中心のz座標をz=0 とする。重力加速 度の大きさをgとし,導体板は十分に広いものとする。以下の間いに答えよ。 数式を求める問題では、m, ソレノイド Zn -0 O 荷電粒子 荷電粒子 ア ソレノイド |R d ー = X 0E 図2 図3 Q V, d.

第3回 実戦問題 73 Vou are going to have a debate about men taking parental leave. In order to prepare for the debate, your group is reading the article below. According t0 a recent survey, about 5.14% of new fathers in Japan Love taken parental leave. Over the years, the number of men who take 18u0 narental leave has grown, but it is still a big challenge for men to take it in male-oriented-Japanese society. So, here is my question: Do you think more Japanese men should take parental leave or not? Taking parental leave has one great benefit. If men take it for even a couple of weeks after the baby arrives, it is a great help to their wives. Most families are now nuclear families, so it is more difficult for couples with a new child to get support from their parents. Husbands can provide not only physical support but also mental support to their wives. Since new mothers face many unexpected situations every day, they can feel a lot of stress. Getting help is the key to reducing it. Another benefit is that parental leave is usually refreshing for men, allowing them to work more efficiently after they return to their jobs. On the other hand, there are reasons men should not take it. (First, during parental leave, they get no salary. This can put a lot of pressure on family finances. Second, many people are still against men taking it, which places psychological pressure on the men who do. What do you think about this issue? Ibelieve that when men take parental leave, it helps them understand how hard caring for a baby is. Knowing more about the hard work of their wives surely strengthens their relationship. Furthermore, when men eagerly raise their children, Tamily bonds become stronger. Nobody could argue that such things should be not be encouraged. 第3回 don

To find out the answer, scientis did some research on two groups of hamsters: one group was given six-hour delays in their daily cycle for four weeks while the other kept their usual cycle. After that, the 10 hamsters were tested on their learning abilities. The result was clear. The hamsters with jet lag had great trouble with simple work which the others could easily do. The researchers also saw this difference evena month after the hamsters with jet lag returnel to their usual daily cycle. They say that the loss of a usual daily cycle damages the part u the brain which controls memory. This causes long-term* memory problems.

One time we even played at a wedding, and we got $250 for that. Son: Not bad. $50 ア Father: No. $62.50. We didn't pay Larry because he forgot to bring his guitar to the wedding. Anyway, with that money we recorded a song that I wrote, called "Happiness Is." Son: Then what happened? Father: Well, we talkeda guy at the record store イ selling the song in his store. We received $1 for every song he sold. We stood ウ at the store all day, and we would all become very excited every time someone bought a record. Nearly one hundred people bought copies of “Happiness Is" before the record store stopped carrying our song. Son: Wow. What happened after that?
