Answer:
a

b

Explanation:
From the question we are told that
The current is 
The length of one side of the square 
The separation between the plate is 
Generally electric flux is mathematically represented as

differentiating both sides with respect to t is

=> 
Here
is the permitivity of free space with value

=> 
=> 
Generally the displacement current between the plates in A

=> 
Answer:
It burns easily & It produces a lot of energy
Explanation:
Answer:
a. 11.5kv/m
b.102nC/m^2
c.3.363pF
d. 77.3pC
Explanation:
Data given

to calculate the electric field, we use the equation below
V=Ed
where v=voltage, d= distance and E=electric field.
Hence we have

b.the expression for the charge density is expressed as
σ=ξE
where ξ is the permitivity of air with a value of 8.85*10^-12C^2/N.m^2
If we insert the values we have

c.
from the expression for the capacitance

if we substitute values we arrive at

d. To calculate the charge on each plate, we use the formula below
