Final answer:
Under a normal state, the body is not negatively charged because neutral atoms have a balanced number of electrons and protons, resulting in no net charge.
Step-by-step explanation:
The statement that under a normal state, the number of electrons in the body is said to be negatively charged, is false. Neutral atoms have the same number of electrons as they have protons, resulting in a neutral overall charge.
For macroscopic objects, being negatively charged means that there is an excess of electrons, while being positively charged means there is a depletion of electrons. In the case of a battery, the law of conservation of charge states that the net charge of a closed system remains constant, and hence the number of protons and electrons entering and leaving a battery must be balanced.
