Monday Homework Problem 2.8 Most of you found a linear charge density for the golf tube of around −1.0× 10−7 Cm by modelling the tube as an infinite straight uniform line charge. The golf tube has a radius of about 2.0 cm. What is the magnitude of the electric field at the surface of the golf tube if it is modelled as an infinite line of charge? Select One of the Following: (a) 9.0×104 NC (b) 4.5×104 NC (c) 1.1×106 NC (d) 2.2×106 NC (e) 6.0×103 NC
