In an ideal world of physics where there are no friction forces to mention, answer is zero. The body is not accelerating, so F = ma, where a is the acceleration (a = 0) and m is the mass of 20 kg. So there is no force.

Let’s use your intuition. You are skating with your girlfriend and holding hands. As long as you go in a straight line and don’t move your feet (a = 0), you just coast. You can hold hands forever and nothing pulls them apart (F = 0). Same equations apply.

Answer:

Answer is 0 b'coz there Is No acceleration in this case...

as by formula F=ma

F=20(0)

Therefore F=0
