Why is tension in a massless string same throughout its length?
Is Tension Constant in a Massless String?
Click For Summary
SUMMARY
Tension in a massless string remains constant throughout its length due to the absence of mass. When analyzing a segment of the string with mass Δm, the forces acting on it are T1 to the right and T2 to the left. The force equation T2 - T1 = Δma indicates that since Δm equals zero, T2 must equal T1. This confirms that tension is uniform across the entire length of the massless string.
