Can you explain the answer of this question below:The charge on a glass rod that has been rubbed with silk is called positive:A:so that the proton charge will be positiveB:because like charges repelC:to conform to the conventions adopted for G and m in Newton&#8217;s law of gravitationD:by arbitrary conventionThe answer is d.

Answer

Ys ... D is correct opt.. as..When a glass rod is rubbed with silk... electrons are transferred.. from the glass rod to the silk..Since the glass rod losses electrons...it becomes rich in positive charge...Similarly... the silk cloth becomes negatively charged.... This phenomenon is called the triboelectric effect

Answer

When the point is on the diameter and away from the centre of hemisphere which is charged uniformly and positively, the component of electric field intensity parallel to the diameter cancel out. So the electric field is perpendicular to the diameter.

Answer

Electrons from glass rod jumps to silk cloth . and hence deficiency of eectrons in glass makes its charge positive

Answer

D

Answer

The answer to this question is option D: by arbitrary convention. Let's break down and explain this answer in detail.

Explanation:

Charge on a Glass Rod
When a glass rod is rubbed with silk, it acquires a positive charge. This means that it gains excess positive charges or loses negative charges, resulting in an overall positive charge on the glass rod.

Convention
The reason why the charge on a glass rod rubbed with silk is called positive is because of an arbitrary convention that has been adopted in the field of electricity. This convention helps in standardizing the terminology and understanding of electrical phenomena.

Arbitrary Convention
By definition, the charge acquired by a glass rod rubbed with silk is labeled as positive. This convention was established based on historical observations and experiments, and it has been widely accepted and used in the field of electricity.

Proton Charge
It is important to note that the reason for calling the charge positive is not related to the charge of protons. Protons are subatomic particles that carry a positive charge, but the naming of the charge on the glass rod is not directly linked to the charge carried by protons.

Like Charges Repel
Option B suggests that the charge on the glass rod is positive because like charges repel. While it is true that like charges repel each other, this is not the reason for labeling the charge on the glass rod as positive. It is a separate concept related to the behavior of charges.

Newton's Law of Gravitation
Option C suggests that the charge on the glass rod is positive to conform to the conventions adopted for G and m in Newton's law of gravitation. However, the charge on the glass rod is not related to Newton's law of gravitation, which deals with the gravitational force between masses, not charges.

Conclusion
In conclusion, the charge on a glass rod that has been rubbed with silk is called positive by arbitrary convention. This convention helps in standardizing the terminology and understanding of electrical phenomena. It is important to differentiate this convention from the charge carried by protons or the behavior of charges.
