The net electric force acting on a positive test charge at the origin is determined as ¹/₉(kq₁q₂).
<h3>Net electric force on the charges</h3>The net electric force on the charges is calculated as follows;
F = kq₁q₂/r²
where;
- k is coulomb's constant
- q₁ and q₂ are the charges
- r is the distance between the charges
Thus, the net electric force acting on a positive test charge at the origin is determined as ¹/₉(kq₁q₂).

Let the height where we are trapped is H
now to find the time to reach the key at the bottom is given as
now we have
now if the speed of sound is considered to be 340 m/s then time taken by the sound to reach at the top is given as
now the total time is given as
now by solving above equation we have
H = 48 m
now height of one floor is 3 m
so our position must be
