Answer:
The value is
Explanation:
From the question we are told that
The mass of the car is
The acceleration is 
Generally the net force applied on the rope is mathematically represented as

Here W is the weight of the car which is evaluated as
=> 
=> 
Generally the net force can also be mathematically represented as
So

=> 
=>
The answer is actually 36 J.

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
