Answer 1

Given Data parallel plate Capacitor Area of plate A = 1.0x162 m² sepration between plate d= 0.2 mm dielectrie constant k = 8.1 Step. I capacitances of capacitor with heletre constant k is given by I where esa permitivity le = keo of air medien &o=8.85 81012 2/4-12 capacitance So Co 2.1 x 885000 12 x 1.0x10² 0.82x103 = 22.66 x 10F 7 = 226.6 PF Step 11 Charge on capaeltor plate is 4.1 MC. PARTA potential difference between plate is given by v= a - charge cha v=4.88106 = 0.180x15 22.66 X17" lv = 18.0kV le PART-B v=0 mens vat & cak) if this increased than c also increased but voltage decreased Ans Decreased
