Suppose two nearby conductors carry the same negative charge. Can there be a potential difference between them? If so, can the definition of capacitance, C = Q/V, be used here?
If two nearby conductors carry the same negative charges means does it carry the potential difference between them, if so capacitance can be used here.
Answer to Problem 1Q
Yes, there will be potential difference between the two nearby conductors carry the same negative charges, and definition of capacitance cannot be used here.
Explanation of Solution
Suppose two nearby conductors carry same charges, there would be potential difference because they have different charge densities. When they have same amount with same sign charges then there would zero potential difference.
So, that the definition of capacitance
Conclusion:
Yes, there will be potential difference between the two nearby conductors carry the same negative charges, and definition of capacitance cannot be used here.

The directions are shown relative to north: 0° is north, 90° is east, 180° is south, and 270° is west. Use the method of components to find (a) the distance she has to fly from Manhattan to get back to Lincoln, and (b) the direction (relative to north) she must fly to get there. Illustrate your solutions with a vector diagram.

- 3.19 • Win the Prize. In a carnival booth, you can win a stuffed gi- raffe if you toss a quarter into a small dish. The dish is on a shelf above the point where the quarter leaves your hand and is a horizontal dis- tance of 2.1 m from this point (Fig. E3.19). If you toss the coin with a velocity of 6.4 m/s at an angle of 60° above the horizontal, the coin will land in the dish. Ignore air resistance. (a) What is the height of the shelf above the point where the quarter leaves your hand? (b) What is the vertical component of the velocity of the quarter just before it lands in the dish?
