Free Body Diagrams
Match the block diagrams of block of mass, m, with their corresponding free body diagram.
(Bodies are at rest with respect to ground)
P - (i); Q - (iii); R - (iv); S - (ii)
P - (ii); Q - (ii); R - (iv); S - (ii)
None of these
P - (i); Q - (iii); R - (iv); S - (iv)
Case 1: Force on lighter vehicle
Case 2: Force on heavier vehicle
- Case 1
- Case 2
Two blocks are in contact on a frictionless table masses 2m and m respectively as shown in figure. Force F is applied on mass 2m then system moves towards right. Now the same force F is applied on m. The ratio of force of contact between the two blocks will be in the two cases respectively.
1 : 1
1 : 4
1 : 2
1 : 3
Three blocks of masses 2 kg, 3 kg and 5 kg are connected to each other with light string and are then placed on a frictionless surface as shown in the figure. The system is pulled by a force F = 10 N, , then tension T1=
Three masses of 15 kg. 10 kg and 5 kg are suspended vertically as shown in the fig. If the string attached to the support breaks and the system falls freely, what will be the tension in the string between 10 kg and 5 kg masses. Take g=10ms−2 . It is assumed that the string remains tight during the motion
Two blocks of mass 4 kg and 6 kg are placed in contact with each other on a frictionless horizontal surface. If we apply a push of 5 N on the heavier mass, the force on the lighter mass will be
None of the above
