Physics 2 questions:
1. You have a positively charged object. How can you use it and another neutral object to place a net negative charge on an insulated metal sphere? Explain in 100 words or less.
2. Consider the following statment: "If you have a Gaussian cube with no charges within it, there is no electric flux through each face of a Gaussian cube for a total of zero flux." Is the statement true or false? Explain your answer in 100 words or less.
3. If the electric field at a particular point in space is equal to zero, can you conclude that no charges are nearby. Explain your answer in 100 words or less.
4. Explain in your own words physically how or why when capacitors are hooked up in series, the equivalent capacitance goes down. Explain in 100 words or less.
Thank you
Explanation / Answer
Question (1): You have a positively charged object. How can you use it to place a net negative charge on an insulated metal sphere?
According to the induction method, when a charged object is brought near to an uncharged and neutral object, the opposite charge is induced on to the surface of neutral body. This is happening due to the electrostatice attractional forces.
Applying the same phenomenon for the given problem, the required charge can be generated on to the surface of insulated metal sphere.
When a positivey charged object is brought bear to neutral and insulated object, the negative charge is induced on to the surface of neutral body, by the induction method, which is due to the electrostatic attraction forces.
