We have 6 levels and we will verify which of them is true.
<em>A ) Electric charge is conserved </em>
According to the conservation of charge, an electric charge can neither be created nor be destroyed.
Therefore this statement is TRUE.
<em>B ) A positive charge and negative charge attract each other</em>
According to the properties of charges, the opposite charges attract each other and similar charges repel each other
Therefore this statement is TRUE
<em>C) Two positive charges attract each other.</em>
Using the previous law, we can observe that this statement is false, because equal charges repel each other.
Therefore this statement is FALSE.
<em>D ) Two negative charges repel each other.</em>
Using the same principle as the two previous statements, two equal charges repel each other.
Therefore this statement is TRUE
<em>E) Electric charge is quantized.</em>
According to the quantization of charge, charges can take values only in integral multiples of a fundamental unit of charge.
Therefore this statement is TRUE.
<em>F) A neutral object contains no charge.</em>
A neutral object contains equal amount of negative and positive charge. Thus, in totality a neutral object contains no charge.
Therefore this statement is TRUE.
