Question

A very long, thin wire fixed along the x axis has a linear charge density of 7.6 pC/m. (a) Determine the electric field at point P a distance of 0.35 m from the wire. (Enter the magnitude.) N/C (b) If there is a test charge 40 = +8.0 PC at point P, what is the magnitude of the net force on this charge? N Enter a number, In which direction will the test charge accelerate? perpendicular to and toward the wire parallel to the wire perpendicular to and away from the wire Submit Answer Viewing Saved Work Revert to Last Response

Answer 1

due a Electric to field long wire 0.35 m с given zator da charge density r = perpendicular distance from tue where to the observation point. Direction of this field is always dicular to the perpen wire 7.64Lm :7,6 X10-6 CM X = 7 E 7.6 X10-6 21 X 0.35 X 8.854X10-12 S the À E = 3.9 X 10 N/L since po sitive so Direction of field a the wire the away from and perpendicular i wire CS Scanned with CamScanner
