When you sketch the problem, it would look like that shown in the picture. The velocity the airplane should achieve must be 120 km/h in order for it to lift off the ground and take-off. Before this, it has to build up speed in order to reach the final velocity from rest. In rectilinear motion, one of the useful equations used is
2ax = vf² - vi²
For consistency, let's convert km/h to m/s.
120 km/h * (1000 m/1 km) * (1 h/3600 s) = 33.33 m/s
Substituting the values,
2a(280 m) = (33.33 m/s)² - 0²
a = 1.984 m/s
The minimum acceleration is 1.984 m/s.

Explanation:
According to Gauss's law, the electric flux through the circular plates is defined as the electric field multiplied by its area:
The magnetic field around the varying electric field of the circular plates is given by:
Replacing (1) in (2) and solving for :
