Sample questions

1. 1.A uniform metre scale of mass 80 g is to be balanced at the 70 cm mark. Find from where a mass of 60 g must be suspended to do so.
2. 2.The diagram in Fig. 1.28 shows two forces $F_{1} = 5\mathrm{N}$ and $F_{2} = 3\mathrm{N}$ acting at points A and B of a rod pivoted at a point O, such that $\mathrm{OA} = 2\mathrm{m}$ and $\mathrm{OB} = 4\mathrm{m}$. Calculate: (i) the moment of force $F_{1}$ about O. (ii) the moment of force $F_{2}$ about O. (iii) total moment of the two forces about O.
3. 3.A fulcrum divides a crow-bar in the ratio 3:1. What weight will be lifted if an effort of 100 N is applied at the end of its longer arm?
   • A.400 N
   • B.300 N
   • C.100 N
   • D.500 N
4. 4.What is the difference between centrifugal and centripetal force?
   • A.Centripetal force is a real force acting outward, while centrifugal force is a pseudo force acting inward.
   • B.Centripetal force is the real force acting towards the centre of the circular path, while centrifugal force is a pseudo force appearing to act outward in a rotating frame.
   • C.Both centripetal and centrifugal forces are real forces acting towards the centre of the circular path.
   • D.Centrifugal force is the real force required for circular motion, while centripetal force is an apparent effect in a rotating frame.
5. 5.The diagram below (Fig. 1.31) shows a uniform bar supported at the middle point O. A weight of $40\mathrm{gf}$ is placed at a distance $40\mathrm{cm}$ to the left of the point O. How can you balance the bar with a weight of $80\mathrm{gf}$?
