Q1. A small, plastic sphere of mass m = 98 g is attached to a string. There is an electric field of 112 N/C directed along the +x direction. If the string makes an angle θ = 30° with the y axis, what is the charge on the sphere?

Q2. Two 9.00 cm diameter charged disks face each other, 20.0 cm apart. Both disks are charged to - 80 nC.
