Answer 1

We will be solvig this problem using certain concepts of Capacitors.

We know that C. {. E. A d. Given: C- 1. 26 x 10 -3 F &= 2.1 d - 4.17 x 100 m - 12 = 8. 854x10 "Flm a) C. d -3 1.26X 10 × 471x100 E. 20 -12 2.1 x 8.854x10 6.0102 x 103 18.5934 A: 323.24 m 6) Dieletric Strength 60x10° vim Vmax Dielectric Strength xd box10 x 4. TTX 106 Vmax 286.2 V Charge a= CV -3 126 X 10 х 286.2 0.361 C d) Volume Axd 323 24 X H.T7x10-6 3 0.00 1542 m

Therefore,

a) A= 323.24 m²

b) V_max= 286.2 V

c) Q =0.361 C

d) V = 0.001542 m³

Hopee this Helps!!
