A uniformly charged wire is 2.58 m long and 0.15 mm in diameter. You measure the electric field 1.20 cm from the wire's axis, not near either end, and you find it to be 543 kN/C, pointing toward the wire. Find the total charge on the wire. Express your answer with the appropriate units. IH HẢ ? Q = Value Units

Q: This second answer is still incorrect.  Would there be another way to figure this out?   Thanks

Q: 3x - 2y = 19 x + 4y = -3

A: We have given two-equation as 3x-2y=19 ---eq1 and x+4y=-3 --- eq 2

Q: So which one is the correct one.

A:

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
