Question

Two identical beads are attached to free ends of two identical springs of spring constant k equals fraction numerator left parenthesis 2 plus square root of 3 right parenthesis m g over denominator square root of 3 R end fraction Initially both springs make an angle of 60 to the power of ring operator end exponent at the fixed point N. Normal length of each spring is 2R. Where R is the radius of smooth ring over which bead is sliding. Ring is placed on vertical plane and beads are at symmetry with respect to vertical line as diameter. Normal reaction on one of the bead at initial moment due to ring is

  1. fraction numerator m g over denominator 2 end fraction    
  2. fraction numerator square root of 3 m g over denominator 2 end fraction    
  3. mg    
  4. Insufficient data    

The correct answer is: mg

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.
