A train locomotive is pulling two cars of the same mass behind it. Determine the ratio of the tension in the coupling (think of it as a cord) between the locomotive and the first car (FT1) to that between the first car and the second car (FT2), for any nonzero acceleration of the train

The ratio is  

Explanation:

The diagram for this question is shown on the first uploaded image

Here we are assume the acceleration of the train is a

which makes the acceleration of each car a

From the question we are told that

      Considering the second car

 The force causing it s movement  is mathematically represented as

 Considering the first car

 The force causing it s movement  is mathematically represented as

=>  

=>  

=>

=>

it will be pushed away from the source of the electric field. a negative charge in a cloud induces a positive charge in the ground below the cloud.
