Question

A horizontal pull A pulls two wagons over a horizontal frictionless floor, the first wagon is 500N, the second is 2000 N. The tension in the light horizontal rope connecting the wagons is.

help explain your answer

Answer 1

Since you said horizontal frictional surface and did not mention any accceleration the tension has to be zero as long as they are moving with constant velocity.

Answer 2

the options to the question are:
a) equal to A, by Newton’s third law.
b) equal to 2000 N.
c) greater than A.
d) less than A.
do you mean a

Answer 3

Now I uderstood the question properly...the tension in the string connecting the wagons in (2000/2500)*A
So the tension is not zero but the answer is option (d)
tension is 0.8*A

Answer 4

sorry for the confusion i left out the options, and thnx
