Every time a constructor is invoked, its base class's constructor is also required to be invoked. Additionally, you can use another class's constructor within the class. Java upholds this principle by requiring that the constructor's first call be to this or super.
Classes will never be used without the necessary initialization because of the requirement that they call the constructor of their superclass. This is important for the security of the Java Virtual Machine (JVM) because some methods won't function until the class has been initialized.

On the y axis, the distance is 1.696*10^(-7) m.
What is electric field?The physical field that surrounds electrically charged particles and exerts force on all other charged particles in the field, either attracting or repelling them, is known as an electric field. It also refers to the physical field of a charged particle system. The electric field may be thought of as an electric property associated with every place in space where a charge exists in any form. The electric force per unit charge is another way to characterize an electric field.
Here,
The proton to produce this field at the origin should be put on m on the y axis.
The calculation is as follows:
We are given the electric field as;
This is written in (x, y, z) co-ordinates. So it means that it lies on the y-axis.
So,
in the y direction.
The Formula for Electric field is;
E = kq/r²
where;
k is a constant with a value of 8.99 x 10^(9) N.m²/C²
q is charge on the proton = 1.6 × 10^(-19) C
r is the distance
Thus, making r the subject gives;
r = √(kq/E)
Now Plugging in the relevant values gives;
r = √(8.99 × 10^(9) × 1.6 × 10^(-19)/(5 × 10⁴))
