4. A uniform, plastic meterstick of mass 48 g is set horizontally across the span between two tables so that its center is located exactly midway between the tables and its ends are barely on each table. (a) What is the magnitude of the force exerted by each table on the meterstick? (b) An 80 g mass is placed on the meterstick at the 80 cm mark. Now what is the magnitude of the force exerted by each table on the meterstick?
