question 49

Multiple Choice

A massless meter stick on a horizontal frictionless table top is pivoted at the 80-cm mark.A force is applied perpendicularly to the end of the stick at 0 cm, as shown.A second force (not shown) is applied perpendicularly at the 60-cm mark.The forces are in the plane of the table top.If the stick does not move, the force exerted by the pivot on the stick:

• A)must be zero
• B)must be in the same direction as and have magnitude
• C)must be directed opposite to and have magnitude
• D)must be in the same direction as and have magnitude
• E)must be directed opposite to and have magnitude
