In-class question

How does the force exerted on the mass B by the string (T) compare with the weight of body B? (Assume a frictionless, massless pulley)

BLUE: T = mB g.

YELLOW: T < mB g.

PINK: T > mB g.

GREEN: not enough information

 

Suppose I now tell you mB is larger than mA.

What is your new answer?
