Question

Statement - I One end of ideal massless spring is connected to fixed vertical wall and other end to a block of mass m initially at rest on smooth horizontal surface. The spring is initially in natural length. Now a horizontal force F acts on block as shown. Then the maximum extension in spring is equal to maximum compression in spring.

Statement - II To compress or to expand an ideal unstretched spring by equal amount, same work is to done on spring.

  1. Statement-I is true, Statement-II is true; Statement-II is NOT a correct explanation for statement-I    
  2. Statement-I is false and Statement-II is true    
  3. Statement-I is true, Statement-II is true ; Statement- II is correct explanation for Statement-I    
  4. Statement-I is true, Statement-II is false    

The correct answer is: Statement-I is true, Statement-II is false


    ) Statement- I is false, Statement-II is false

    A machine, in an amusement park, consists of a cage of the end of one arm, hinged at O. The cage revolves along a vertical circle of radius r (ABCDEFGH) about its hinge O, at constant linear speed v= square root of g r end root . The cage is so attached that the man of weight 'W' standing on a weighing machine, inside the cage, is always vertical. Then which of the following is correct
