Two unequal weights are connected by a massless string which passes over a frictionless pulley.  If the pulley has no appreciable mass, the tension in the string is the same on both sides of the pulley; but if the pulley has mass, the tension will not be the same on both sides of the pulley.Group of answer choicesFalseTrue

Two men of unequal masses hold on to the two sections of a light rope passing over a smooth light pulley. Which of the following are possible?

Two identical masses are attached by a light string that passes over a small pulley, as shown above.The table and the pulley are frictionless.The masses are movingGroup of answer choiceswith an acceleration equal to g.with an acceleration greater than g.with an acceleration that cannot be determined without additional information.at constant speed.with an acceleration less than g.

A double pulley is free to rotate about its axis through its center. The radii of the two pulleys are   and  . Two cords are wrapped in opposite directions on the pulleys and are attached to masses. As a result, the two tension forces acting on the pulley are equal and acting downwards as shown in the image below so that  .

Two blocks are connected by a (massless) string that passes over a (massless, frictionless) pulley as shown. Assume the interface between block A and the horizontal tabletop to be frictionless. If mA = 8 kg and mB = 8.7 kg, what is the tension in the string?Express your answer in N, to at least one digit after the decimal point.

A mass m1 is connected by a light string that passes over a pulley of mass M to a mass m2 sliding on a frictionless horizontal surface as shown in the figure. There is no slippage between the string and the pulley. The pulley has a radius of 25.0 cm and a moment of inertia of ½ MR2. If m1 is 4.00 kg, m2 is 4.00 kg, and M is 4.00 kg, then what is the tension in the string attached to m2?
