Question

3. A charged object is made of three equally charged rods: as shown. Five points are indicated. All points are the same distance from the nearest rod (a) Rank the electric potential at each of the labeled points, from greatest to least (b) Suppose middle, positively charged rod were replaced with an identical, negatively charged rod. Would the magaitude of the electrie field at each point (A-E) increase, decrease, or remain the same? Would the value of the electrie potential at each point (A E) increase, decrease, or remain the same?

Explanation / Answer

1)The order would be c , b , d , a , e

Since c is the nearest to all the parts of the object , it would have the highest potetial.

In case of b and d, b is near to two positivel charged parts when compared to d which is near one positively charged and one negatively charged part.

The same above reason is valid for the cases a and e

2) a- Decrease

b- Decrease

c- remains same

d-Increase

e-Increase
