UL- 3. In the figure, the blocks A, B and C of mass m each have acceleration a,, a, and a, respectively. F, and F₂ are external forces of magnitudes 2 mg and mg respectively. 1) a₁ = a₂ = a3 2) a, > a₂ > az 3) a₁ = a₂, a₂ > a3 4) a₁ = a₂, a₂ a3 21N 15cm Numerical Value Type Questions 4. A uniform rod of length 60 cm and mass 6kg is acted upon by two forces as shown in the diagram. The force exerted by 45 cm part ofthe rod on 15 cm part of the rod is N. b) acceleration of the system is 2kg F M+m 45cm F m+M, m A 5. Two masses 5kg and 2kg connected by a string are at rest on a smooth horizontal surface. A con- stant force 1N is applied on 5kg mass as shown in the figure. Two seconds later the string connect- ing the masses is cut but 'F' continues to act. After two more seconds, velocity of lighter body is m/s MF M+m F₁=2mg LEVEL-II (ADVANCED) More than One correct answer Type Questions 1. A vertical force of magnitude F acts at the top of a string of mass 'm' and length 7. A body of mass M hangs at the bottom of the string. a) acceleration of the system is -g C 45N F₂= mg F Figure-1 ny=1 M Oman c) tension in the string at y = 0 is d) tension in the string at y = 1 is F 2. A block of mass 'm' is raised by a man of mass m₂ in two different ways as shown (m₁ = 25kg, m₂ = 50kg) a) The action of the man on the floor in first case is 750N b) The action of the man on the floor in second case is 250N c) The action of the man on the floor in first case is 250N d) The action of the man on the floor in second case is 750N ELITE SERIES for Sri Chaitanya Jr. ICON Students y=0 ummaar kurz Figure-2 Oman GTTT 139 A VC Sri Ch 11 UL- 3.
