    Induction
In summary, a positively charged rod placed near a conducting sphere on an insulating surface will produce a negative charge on the sphere through polarization, rather than through conduction, induction, or convection. This is because the negative charge will not be able to flow to the rod, leaving the sphere with a net negative charge.

Homework Statement



By what method will a positively charged rod produce a negative charge on a conducting sphere that is placed on an insulating surface.

Homework Equations



a) by means of conduction b) by means of induction c) by means of convection d) none of the choice are correct

The Attempt at a Solution



I am guessing d because the rod will only be able to polarize... and if it was conducted the negative charge would flow to the rod which will leve the sphere positive...

hi freeofwork :smile:

well, it's obviously not conduction or convection, and i don't think it comes within the strict definition of induction, so that does leave d) :wink:
 

FAQ: Positive Charge Induction on Insulating Sphere

What is induction?

Induction is a scientific method used to make generalizations based on specific observations or data. It involves using past experiences or observations to make predictions about future events or phenomena.

How is induction used in science?

In science, induction is used to formulate hypotheses and theories based on observations and experiments. It allows scientists to make predictions and test them through further observations or experiments.

What is the difference between induction and deduction?

The main difference between induction and deduction is that induction involves making generalizations from specific observations, while deduction involves deriving specific conclusions from general principles or theories.

What are the limitations of induction?

One of the limitations of induction is that it is based on probability and not certainty. This means that even if a hypothesis is supported by many observations, it is still possible for it to be proven wrong in the future. Additionally, induction cannot prove causality, only correlations.

Why is "induction or nothing" a controversial concept?

"Induction or nothing" is a controversial concept because some argue that induction is not a reliable method for gaining knowledge. They argue that it is based on assumptions and cannot provide absolute truths. Others argue that induction is a necessary and valuable tool in scientific inquiry.
