Jim blindfolds Dwight and gives him a 4lb weight to hold. He then takes back the 4lb weight, and gives Dwight a 6lb weight. Dwight claims to notice the difference between the two. Assume that these values represent Dwights just noticeable difference for weight (i.e., Dwight would not notice the difference if given a 5.9lb weight). Jim then gives Dwight a 50lb weight. According to Webers Law, which of the following weights could Jim give Dwight next for him to notice a difference?.
