Sample questions

1. 1.One end of a string of length l is tied to a particle of mass m and the other to a peg on a smooth horizontal table. The particle moves in a circle with speed v. If T is the tension in the string, the net force on the particle directed toward the centre is:
   • A.T - mv^2/l
   • B.T + mv^2/l
   • C.T
   • D.zero
2. 2.According to Aristotle's view of motion, what is required to keep a body moving?
   • A.A continuous external force
   • B.Zero net force
   • C.An impulsive force only at the start
   • D.Only the force of gravity
3. 3.![fig_4_12_block_trolley.png]() In the free-body diagram (c) of the trolley, the two horizontal forces shown are the string tension T and:
   • A.The kinetic friction f_k
   • B.The weight W
   • C.The normal reaction N
   • D.The centripetal force
4. 4.Momentum is a:
   • A.Scalar quantity
   • B.Vector quantity
   • C.Dimensionless quantity
   • D.Quantity with no direction
5. 5.A stone tied to a string is rotated in a vertical circle of radius 0.9 m. The minimum speed at the topmost point so that the string stays taut is (take g = 10 m/s^2):
   • A.3 m/s
   • B.9 m/s
   • C.1.5 m/s
   • D.6 m/s
