A straight wire 10 m long carries $25 \mu C$ distributed uniformly over its length. (a) What's the line charge density on the wire? Find the electric field strength (b) $15 \mathrm{cm}$ from the wire axis, not near either end, and (c) 350 m from the wire. Make suitable approximations in both cases.

Step 1
Given: Total charge on the wire, Q = $25 \mu C$ Total length of the wire, L = 10 m The line charge density, λ, is given by: \[ \lambda = \frac{Q}{L} = \frac{25 \times 10^{-6} C}{10 m} = 2.5 \times 10^{-6} C/m \] Show more…

A very long, thin wire fixed along the x-axis has a linear charge density of 3.2 µC/m. a) Determine the electric field at point P, a distance of 0.50 m from the wire. b) If there is a test charge q0 = 2.0 µC at point P, what is the magnitude of the net force on this charge? In which direction will the test charge accelerate?
