заряд q1=q создает в точке А электрическое поле напряженностью Е. какой станет величина напряженности поля в этой точке если в точку В дополнительно поместить заряд q2=q, решения объяснить

Ответы

Автор ответа: Аноним

напряженность поля от заряда q1 в точке А E1 = q1* k/r^2=q* k/r^2

напряженность поля от заряда q1+q2 в точке А E12 = (q1+q2)* k/r^2=2q* k/r^2 = 2E1

объяснение - увеличится в ДВА раза

Social Structure and Individuality

The assertion that human behavior is socially patterned often provokes some initial resistance. Few human beings readily admit to being part of any kind of system, especially those who live in a culture that prizes individual autonomy. Americans, for instance, tend to emphasize individual responsibility for behavior and highlight the unique elements of their personalities. Behaving in patterned ways, however, does not threaten our individuality. On the contrary, individuality is encouraged by social structure.
First, and more generally, our humanity involves much more than physical existence. The great potential of human beings develops only thorough interaction with others. Within social life, distinct personalities emerge as people blend their unique qualities with the values and norms of the large culture from freely expressing ourselves. The social world can be disorienting, even frightening, to people who do not know the behavior guidelines. Without this knowledge, people feel too uncomfortable to express their unique personalities with confidence.
To illustrate, you may recall going alone to a party given by people you did not know well. Entering such a setting – and not knowing quite what to expect – is likely to cause some anxiety. At such times you generally feel self-conscious, try to make a favorable impression, and look to others for clues about what sort of behavior is expected of you. Once you understand the behavioral standards that apply to the setting, you are likely to feel comfortable enough to «act like yourself».
Of course, social structure also places some constraints on human behavior. By guiding behavior within culturally approved bounds, established social patterns discourage behavior that is culturally defined as unconventional. Traditional values and norms in the United States and Canada, for example, still reflect the expectation that males will be «masculine» (physically strong, self-assertive, and rational) and the females will be «feminine» (physically weak, self-effacing, and emotional). The structure of society exerts pressure on individuals to fit into one or the other of these categories, ignoring the fact that most people have both «masculine» and «feminine» qualities. In this and many other ways, social structure can limit any individual's freedom to think and act in ways that may be personally preferred. In addition, the failure to conform to established social patterns may lead to being defined by others as deviant.
