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