The electric field for 20 cm is 8.09 MN/C
Length of the straight filament = (20cm) (1m/100cm) = 0.2
Electric field for the straight conductor =
E = [2(8.99 × 10^9 N·m^2/C^2)(90.0 × 10^-6 C/m)] / 0.2 m
E = 8.09 MN/C
The electric field is directly radially inward, toward the filament.
Electric field is a force produced by a charge near its surroundings. This force is exerted on other charges when brought in the vicinity of this field. SI unit of electric field is N/C (Force/Charge).

In an uniformly accelerated motion, the velocity of the object follows the law:
where
is the initial velocity, a the acceleration and t the time.
In our problem, the robot starts from rest, so the initial speed is zero:
. The robot is in free fall, so the acceleraion is the gravitational acceleration 
. therefore, after a time 
, the velocity is
where
In our problem, the robot starts from rest, so the initial speed is zero:
