The system shown adjacent is in equilibrium. Blocks are of equal masses (Assume springs to be ideal).
Then choose the correct statements.


Important Questions on Laws of Motion

A mass is attached to two springs as shown in figure. The spring constants of two springs are and For the frictionless surface, the time period of oscillation of mass is










Two identical springs are connected to mass as shown . If the period of the configuration in (i) is , the period of the configuration (ii) is:
I
II


The machine as shown has rods of length connected by a pivot at the top. The end of one rod is connected to the floor by a stationary pivot and the end of the other rod has roller that rolls along the floor in a slot. As the roller goes back and forth, a weight moves up and down. If the roller is moving towards right at a constant speed, the weight moves up with a :





(density of water is )




As shown in the figure, an iron block of volume is attached to a spring of unstretched length and hanging to the ceiling of a roof. The spring gets stretched by . This block is removed and another block of iron of volume is now attached to the same spring and kept on a frictionless incline plane of inclination. The distance of the block from the top along the incline at equilibrium is

A block of mass is suspended through two spring balances with negligible mass as shown in figure. What will be the readings in the upper and lower balance respectively ?
