To explain: The properties of both positively and negatively charged objects that can attract neutral objects.

Explanation of Solution
Introduction:
The force of attraction or repulsion between the electrically charged particles is known as electrostatic force. There will be a force of attraction acting between the unlike charges and force of repulsion between the like charges. The electrostatic force possesses small range that is about only one tenth of the nucleus diameter, that is
Charge separationis caused because unlike charges attracts each other and the like charges repels one another. Because of this charge separation, when the charged object is held nearer to a neutral object, the opposite charges in the neutral object moves closer to the charged object and the like charges moves farther away. Inverse relationship exists between the electrostatic force and the distance between the charges. Because of this, the attractive force between the nearer opposite charges is more than the repulsive force between the distant like charges. The total effect isattraction. These two effects explains how both positively and negatively charged objects can attract neutral objects.

- Suppose there are two transformers between your house and the high-voltage transmission line that distributes the power. In addition, assume your house is the only one using electric power. At a substation the primary of a step-down transformer (turns ratio = 1:23) receives the voltage from the high-voltage transmission line. Because of your usage, a current of 51.1 mA exists in the primary of the transformer. The secondary is connected to the primary of another step-down transformer (turns ratio = 1:36) somewhere near your house, perhaps up on a telephone pole. The secondary of this transformer delivers a 240-V emf to your house. How much power is your house using? Remember that the current and voltage given in this problem are rms values.arrow_forwardThe human eye is most sensitive to light having a frequency of about 5.5 × 1014 Hz, which is in the yellow-green region of the electromagnetic spectrum.
