Problema 5
A 20 g non-conducting cuboid lying at rest on a 25 degrees incline has a total charge of 8.0 × 10-6 C. The friction coefficients between the cuboid and the incline are µs = 0.15 and µk = 0.080. If the setup lies in a horizontal electric field, what least electric field strength is required to keep the cuboid from sliding?
