Question

Constants Part A Two very long uniform lines of charge are parallel and are separated by 0.260 m. Each line of charge has charge per unit length 5.00 C/m What magnitude of force does one line of charge exert on a 4.20102 m section of the other line of charge? Express your answer to three significant figures and include the appropriate units.

Explanation / Answer

E = [1 / 2 pi e0] * [lambda / r]

E = (2 * 9 * 109 * 5 * 10-6) / (0.260) = 3.46 * 105 N/C

q = lambda * d

= 5 * 10-6 * 4.2 * 10-2 = 2.1 * 10-7 C

F = E q

= 3.46 * 105 * 2.1 * 10-7

magnitude of force = 0.0727 N
