Which of the following are true statements? a. like charges repel b. unlike charges repel c. unlike charges attract or d. charged objects attract neutral object due to induction

The correct answers are (A) and (C).

Explanation:

The expression from electrostatic force is as follows;

Here, F is the electrostatic force, k is constant, r is the distance between the charges and are the charges.

The electrostatic force follows inverse square law. It is inversely proportional to the square of the distance between the charges. It is directly proportional to the product of the charges.

Like charges repel each other. There is a force of electrostatic repulsion between the like charges. Unlike charges attract each other. There is a force of electrostatic attraction between unlike charges.

The charges are induced on the neutral object when it is placed nearby the charged object without actually touching it.

Therefore, the true statements from the given options are as follows;

Like charges repel.

Unlike charges attract.

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

truck y has a greater velocity than truck x.
