Avery long wire carries a uniform linear charge density λ. using a voltmeter to measure potential difference, you find that when one probe of the meter is placed 2.30 cm from the wire and the other probe is 1.50 cm farther from the wire, the meter reads 550 v . a) what is |λ|?
b) if you now place one probe at 3.30 cm from the wire and the other probe 1.50 cm farther away, will the voltmeter read 550 v , more or less than 550 v ?

Part a)

Part b)

So it is more than 550 V

Explanation:

As we know that the electric field due to linear charge density is given as

now we know that potential difference between two points is given as

Part a)

Now we know that potential difference between two points at distance r = 2.30 cm and r = 1.50 cm is given as 550 V

Part b)

Now we know that potential difference between two points at distance r = 3.30 cm and r = 1.50 cm is given as

So it is more than 550 V

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
