Ответ:

Дано:

q1=2 нКл;

q2=6 нКл;

r=2 см=2*10^-2 м.

Знайти F.

Сила, з якою взаємодіють між собою заряди, визначають за формулою: F=(|q1|*|q2|)*k/r^2, де k=9*10^9 Н*м^2/Кл.

Тоді F=(2*10^-9)*(6*10^-9)*9*10^9/(2*10^-2)*(2*10^-2)=2,77*10^-4 Н=0,27 мН.

Відповідь: 0,27 мН.

The Clown Doctor



When a child is in hospital, away from his parents and his home, he usually feels sad, lonely and in pain. This is where clown doctors can help. They treat children in hospitals with medicines of a different kind… fun and laughter! Children can forget about their illnesses for a moment and return to a world of happiness and play. It is hard to keep a sad face when clown doctors come in!

This is what Liz, a 23-year-old clown doctor from London, says.

«With children who are ill I am a clown doctor. I spend two days a week in children’ s hospitals. It’s not enough just to feel sorry for children. I play with sick children, sing songs, make funny faces and do tricks. I tell them funny stories about different things. I often meet children who look really sick one week, then I come back the next week and they run about looking happy.

I am a very happy person by nature. I’ve a been a clown for several years. In fact, my father is a clown too. I started working with him when I was eight years old. I became a clown doctor because I think it’s great to help sick children in hospitals. I wear an unusual coat, a yellow shirt and trousers with big stars. I’ve got a big red nose and my hair is red, too.

To be a clown in a hospital is very hard. I have learnt not to show what I feel. To the children I am always happy, I laugh all the time. But I know that some children are very ill. It makes me unhappy.

At lunchtime I meet nurses and doctors. They tell me about the children who need my help, the children who have terrible pains or run a high temperature, the children who don’t want to take medicines and don’t let doctors examine them.

At six o’clock in the evening I change my clothes. I am very tired. I often go out with my friends and tell them about my little patients. When I finally go to bed, I sometimes can’t fall asleep. I understand my problems are really small when I remember those sick children. When I am among them, they forget about pain. In fact, I am proud to be a clown doctor because I do my best to help them to recover. »
