94 95 In the system shown in the figure the acceleration of 1 kg mass is a downwards 4 b downwards 8 c upwards d upwards 96 Two blocks of masses 8 kg and 12 kg are connected at the two ends of a light ipextensible string The string passes over a frictionless pulley The acceleration of the system is a 8 c b d 97 A monkey of mass 40 kg climbs on a massless rope which can stand a maximum tension of 500 N In which of the following cases will the rope break Take g 10 ms 8 a The monkey climbs up with an acceleration of 5 ms b The monkey climbs down with an acceleration of 5 ms mtG Objective NCERT Phys c The monkey climbs up with a uniform speed 5 ms d The monkey falls down the rope freely under gravity angl 98 A book is lying on the table What is the between the action of the book on the table and the reaction of the table on the book b 45 d 180 a 0 c 90 99 Two blocks of masses of 40 kg and 30 kg are connected by a weightless string passing over frictionless pulley as shown in the figure 40 kg 0 kg The acceleration of the system would be b 0 8 ms 2 a 0 7 ms c 0 6 ms d 0 5 ms 100 A mass of 1 kg is suspended by means of a thread The system is i lifted up with an acceleration of 4 9 ms ii lowered with an acceleration of 4 9 ms The ratio of tension in the first and second case is a 3 1 c 1 3 b 1 2 d 2 1
