The force required is "200 Newtons".

Explanation:

Use the formula

F = ma

to solve this problem. In the case of the "20 N" force, we have

"20 N" = "2 kg" xx a

so

a = "10 m/s"^2 -> read this as 10 meters per second squared, or 10 meters per second every second

Applying the formula again in case of the "20 kg" object, we have

F = ma

F = "20 kg" xx "10 m/s"^2

F = "200 N"
