Question

A uniform linear charge of linear density y= 3.8nC/m, and it extends from x=0 to x=5, what is the total charge in nC?

Answer 1

It extends from x=0 to x=5
so it extends for a length of 5 meters (5-0)
Total Charge= \(y\times length\)
\[=3.8 \ \frac{nC}{m}\times 5 m=?\]
I think you can solve from here
