Card 1 of 21
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 mgcosθ\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.
