Una cubierta cilíndrica con un radio de 5.0 cm y longitud de 2.3 m tiene una carga con distribución uniforme sobre su superficie curva. La magnitud del campo eléctrico en un punto que está a 17.0 cm radialmente hacia fuera del eje de la cubierta es de 20.0 kN/C. Determine (a) la carga neta sobre la cubierta y (b) el campo eléctrico que existe en un punto a 3.0 cm del eje de la cubierta.
Two metal rods, vertically placed and separated, are joined at
the top.
a distance of l = 50cm. The whole, whose resistance is
considered contempt-
It is placed within a uniform magnetic field of flow density B
= 0.01kT perpendicular to the plane defined by the rods. By them,
it slides downwards with constant speed of v = 1jm / s, without
friction and without interrupting the contact, a bar AB whose mass
is m = 1g. Determine the resistance...
