 1.A block in the shape of a parallelopiped of sides lm x 2m x 3m lies on the surface. Which of the faces gives maximum stable block ? 1 m x 2 m 2 m x 3 m 1 m x 3m equally stable on all faces ANSWER : : 2 m x 3 m Explanation :
 2.A solid sphere of mass M and radius R rolls down a plane inclined at 0 with the horizontal. The acceleration of sphere is (1/3) g sin0 (2/5) g sin 0 (3/7) g sin 0 (5/7) g sin0 ANSWER : re g is acceleration due to gravity Explanation :
 3.Minimum potential energy of a system will be in the position of stable equilibrium unstable equilibrium neutral equilibrium all of the above ANSWER : : stable equilibrium Explanation :
 4.A solid cylinder of mass M and radius R rolls down an inclined plane without slipping. The acceleration of centre of mass of rolling cylinder is (1/3) g sinB (2/3) g cos 9 (2/3) g sin 0 g sin 9 ANSWER : re 'g' is acceleration due to gravity and 0 is inclination of plane with hori�zontal. Explanation :
