Answer:
E = 5291.00 N/C
Explanation:
Expression for capacitance is

where
A is area of square plate
D = DISTANCE BETWEEN THE PLATE




We know that capacitrnce and charge is related as


v = 9.523 V
Electric field is given as

= 
E = 5291.00 V/m
E = 5291.00 N/C
It would be kinetic energy. Let's say the book is weighs 10 Newtons you need to use a force of 10 Newtons to lift the book. In other words it's positive. As you move the book you're giving it energy. Namely potential energy which will turn to kinetic energy if you let it go. So you're changing it's position and energy.
