Step 1
We need to find the perimeter of a triangular piece of land to determine how much wire is needed to fence it. We know the lengths of two sides, \(a = 20\) m and \(b = 15\) m, and the angle between them, which is \(70^\circ\). Show more…

Determine el flujo eléctrico en las superficies A y C. Si q = 10 µC. Un alambre delgado y largo, con cientos metros de longitud, tiene una carga uniformemente distribuida de λ = -7.2 µC/m. Estime la magnitud y dirección del campo eléctrico en los puntos (a) 5.0 m y (b) 1.5 m localizados de manera perpendicular desde el centro del alambre. Determine el potencial eléctrico en el punto que se muestra en la figura.
