Question 13 In each case, find the x- and y-components of vector Ā;
(a) A = 5.0i- 6.3j
(b) A = 11.2i - 9.91j
(c) A = -15.0i + 22.4j
(d) Ā= 5.0B, where B = 4i - 6j

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
