77. (a) Since u = 1 2 κε 0 E 2 , we select the material with the greatest value of κE 2 max ,where E max is its di- electric strength. We therefore choose strontium titanate, with the corresponding minimum volume V min = U U max = 2 U κε 0 E 2 max = 2(250 kJ) (310) ( 8 . 85 × 10 12 C 2 N · m 2 ) (8 kV / mm)
