PHYS 152 MIDTERM 3 (Summer 20II) Mo-Tu-W-Th 12:00-13:55 pm (Dr. papp) Student # Name l' (10 pts) An isolated parallel-plate capacitor of arcaA with an afu gap of s is charged up to a potential difference lV. We slide a plastics such that the plastic perfectly fills the gap. The upper half part of the capacitor is filled with plastic with dielectric constant 1(_1, while the lower half is filled with plastic with dielectric constant K_2. a.lwhat is going to be the new potential difference between the plates? b/ What is the capacitance of this capacitor? t ti \ f;') /l v <..'1<< Fl {o / t.'
