Answer:

Explanation:

(a) For the calculation of the Electric field we use

E=\frac{V}{d}=\frac{15.0V}{1.6*10^{-3}m} =9375\frac{N}{C}

(b) The capacitance is calculate by using the expression

C=\frac{\epsilon_{0}A}{d}=\frac{8.85*10^{-12}C^{2}/(Nm^{2})*(7.6*10^{-4}m^{2})}{1.6*10^{-3}m}=4.2*10^{-12}C

(c) Finally, the charge on each plate is

Q=CV=(4.2*10^{-12}C)(15V)=6.3*10^{-11}C

I hope this is useful for you
