Q01 – JEE Main 2013 – Two blocks of mass M1 = 20 kg and M2 = 12 kg are connected by a metal rod of mass 8 kg. The system is pulled vertically up by applying a force of 480 N as shown. The tension at the mid-point of the rod is:

Q02 – JEE Main 2013 – A body starts from rest on a long inclined plane of slope 45°. The coefficient of friction between the body and the plane varies as 𝜇=0.3𝑥, where 𝑥 is the distance travelled down the plane. The body will have maximum speed (for g = 10 ms-2) when 𝑥=

Q03 – JEE Main 2013 – A body of mass ‘m’ is tied to one end of spring and whirled round in a horizontal plane with a constant angular velocity. The elongation of the spring is 1 cm. If the angular velocity is double, the elongation in the spring is 5 cm. The original length of the spring is:

Q04 – JEE Main 2013 – A block is placed on a rough horizontal plane. A time dependent horizontal force 𝐹=𝑘𝑡 acts on the block, where 𝑘 is a positive constant. The acceleration time graph of the block is:

Q05 – JEE Main 2014 – A block of mass m is placed on a surface with a vertical cross section given by 𝑦=𝑥^3/6. If the coefficient of friction is 0.5, the maximum height above the ground at which the block can be placed without slipping is:

Q06 – JEE Main 2014 – A block A of mass 4 kg is placed on another block B of mass 5 kg, and the block B rests on a smooth horizontal table. If the minimum force that can be applied on A so that both the blocks move together is 12 N, the maximum force that can be applied on B for the blocks to move together will be :

Q07 – JEE Main 2014 – Water is flowing at a speed of 1.5 ms–1 through a horizontal tube of cross-sectional area 10–2 m2 and you are trying to stop the flow by your palm. Assuming that the water stops immediately after hitting the palm, the minimum force that you must exert should be (density of water = 103 kg m–3).

Q08 – JEE Main 2014 – A body of mass 5 kg under the action of constant force

Q09 – JEE Main 2014 – A heavy box is to be dragged along a rough horizontal floor. To do so, person A pushes it at an angle 30° from the horizontal and requires a minimum force FA, while person B pulls the box at an angle 60° from the horizontal and needs minimum force FB. If the coefficient of friction between the box and the floor is √3/5, the ratio 𝐹_𝐴/𝐹_𝐵 is:

Q10 – JEE Main 2015 – Given in the figure are two blocks A and B of weight 20 N and 100 N, respectively. These are being pressed against a wall by a force F as shown. If the coefficient of friction between the blocks is 0.1 and between block B and the wall is 0.15, the frictional force applied by the wall on block B is :
