The potential difference between the plates of a parallel plate capacitor is 35 v and the electric field between the plates has a strength of 750 v/m. if the plate area is 4.0 ý 10-2 m2, what is the capacitance of this capacitor?
a. 7.6 ý 10-14 f
b. 7.6 ý 10-10 f
c. 7.6 ý 10-11 f
d. 7.6 ý 10-12 f
e. none of the other choices is correct.

Capacitance will be

So option (d) will be correct option

Explanation:

We have given potential difference across the plate V = 35 volt

Electric field between the plate E = 750 volt/m

Area of the plate

We have to find the capacitance

We know that potential difference is given by

here E is electric field and d is distance between the plate

So

d = 00466 m

We know that capacitance is given by

So option (d) will be correct option
