Two massive springs, are linked together and pulled from opposite ends by Tensio

Question

Two massive springs, are linked together and pulled from opposite ends by Tension forces T1 and T2. The spring constants are NOT the same: k2 >> k1. Both massive springs accelerate to the RIGHT as a result of the tension forces.

Which of the following are true about the tension forces T1 and T2?

Select one:

a. T1 is equal to T2 because it’s a Newton’s third law pair

b. T1 is equal to T2 because of Newton’s Second Law

c. T1 is equal to T2 but neither A not B alone suffices to conclude that.

d. T1 is larger than T2

e. T1 is smaller than T2

Explanation / Answer

Restoring force in the spring is

              F = kx

Here, k is spring constant and x is the compression or expansion.

As the k2 >> k1

tension T2 is larger.

Hence answer is option (e).
