Answer:

Explanation:
From the question we are told that:
Length 
Voltage 
Frequency 
Generally the equation for maximum Electric Field is mathematically given by



Answer:
q = 0.384 C
Explanation:
The total charge present at the head can be easily found out by multiplying the charge on a single electron with the total number of electrons present on the head:

where,
q = total charge on head = ?
n = total no. of electrons on the head = 2.4 x 10¹⁸
e = charge on 1 electron = 1.6 x 10⁻¹⁹ C
Therefore,

<u>q = 0.384 C</u>
