Answer:
Explanation:
Plate separation, d = 1.76 cm = 0.0176 m 
Area of plates, A = 25 cm^2 = 0.0025 m^2 
V = 255 V 
(a) Capacitance of capacitor 


C = 1.258 x 10^-12 F 
charge is same before and after immersion as the battery is disconnected 
q = C V 
q = 1.258 x 10^-12 x 255 = 3.2 x 10^-10 C
(b)
Capacitance before, C = 1.258 x 10^-12 C
capacitance after, C' = k x C = 80 x 1.258 x 10^-12 = 100.64 x 10^-12 C 
Where, k is the dielectric constant of water = 80 
Potential difference after immersion, V' = V / k = 255 / 80 = 3.1875 V 
(c) initial energy,


Final energy
