3.5.4 Model a system of connected particles

Why is tension constant throughout a light string over smooth pulleys?

A

They are internal forces occurring in opposite pairs.

B

The component of weight perpendicular to a slope inclined at θ\thetaθ is mgcos⁡θ\boxed{mg\cos\theta}mgcosθ​.

C

The string has negligible mass, so no resultant force accelerates it.

D

For the complete connected system, only external forces contribute to the resultant force.
