Question

You are in outer space where there is no gravity. You tie a cork to the end of a string and whirl it around in a circle with a constant angular velocity. Which statement is FALSE? The centripetal force on the cork is equal to the tension in the string. The net force on the cork is zero. The speed of the cork is constant. The angular acceleration of the cork is zero. The velocity of the cork is constantly changing. Suppose you are given the three masses shown below with M_1 = 10 kg, M_2 = 160 kg, and an unknown mass m, the distance between m and M_1 is 3 meters. If m experiences no net gravitational force, then what is the distance d from m to M_2? 6 meters 12 meters 15 meters 18 meters 21 meters

Explanation / Answer

14. option a is correct

because only two force are acting on the cork in this case and both should be equal to move in circular path, since there is no verical force so tension is equal to centrifugal force , if gravity is there then horizontal component of tension is equla to centrifugal force.

15.)Gravitational force = Gm1m2/R^2

at equlibrium

GmM1/3^2 = GmM2/d^2

10/9 = 160/d^2

d = 12 meters
