Explanation:
When a charged object is brought near a neutral object without touching each other a charge arises on the neutral object. This method of charge development is known as induced charge.
On the other hand, when a charged object touches a neutral object and then the charged object is removed will lead to the development of a charge on the neutral object. This charge is known as residual charge.
Thus, we can conclude that when a charged body is brought close to an uncharged body without touching it, an induced charge may result on the uncharged body. When a charged body is brought into contact with an uncharged body and then is removed, a residual charge may result on the uncharged body.

The device used to measure a potential difference in a circuit is called a voltmeter. The correct option is c.
The tool used to measure the potential difference between two locations in an electric circuit is called a voltmeter. A voltage meter usually referred to as a voltmeter, is a device that measures the voltage, or potential difference, between two points in an electrical or electronic circuit.
Both of these devices are employed in electric circuits, however, the voltmeter is primarily used to measure the voltage or emf across two points in an electric circuit, whilst the ammeter is mostly used to measure the flow of current.
Depending on the measurement, voltmeters are divided into two categories: DC voltmeters and AC voltmeters.
Therefore, the correct option is c. voltmeter.

Answer:
When a negatively charged object is brought near a positively charged object, an attractive force is produced. ... When a negatively charged object is brought near the knob of a neutral electroscope, the negative charge repels the electrons in the knob, and those electrons move down the stem into the leaves.
Answer:
Suppose that you rubbed a balloon with a sample of animal fur such as a wool sweater or even your own hair. The balloon would likely become charged and its charge would exert a strange influence upon other objects in its vicinity. If some small bits of paper were placed upon a table and the balloon were brought near and held above the paper bits, then the presence of the charged balloon might create a sufficient attraction for the paper bits to raise them off the table. This influence - known as an electric force - occurs even when the charged balloon is held some distance away from the paper bits. The electric force is a non-contact force. Any charged object can exert this force upon other objects - both charged and uncharged objects. One goal of this unit of The Physics Classroom is to understand the nature of the electric force. In this part of Lesson 1, two simple and fundamental statements will be made and explained about the nature of the electric force.
Perhaps you have heard it said so many times that it sounds like a cliché.
Opposites attract. And likes repel.
These two fundamental principles of charge interactions will be used throughout the unit to explain the vast array of static electricity phenomena. As mentioned in the previous section of Lesson 1, there are two types of electrically charged objects - those that contain more protons than electrons and are said to be positively charged and those that contain less protons than electrons and are said to be negatively charged. These two types of electrical charges - positive and negative - are said to be opposite types of charge. And consistent with our fundamental principle of charge interaction, a positively charged object will attract a negatively charged object. Oppositely charged objects will exert an attractive influence upon each other. In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects apart. Similarly, a negatively charged object will exert a repulsive force upon a second negatively charged object. Objects with like charge repel each other.
