Question

STATEMENT-1 : A block of mass m is placed at rest on rough horizontal surface. The coefficient of friction between the block and horizontal surface is mu equals 1 divided by 3. The minimum force F applied at angle theta equals 37 to the power of ring operator end exponent (as shown in figure) to pull the block horizontally is not equal to mmg. (Take s i n invisible function application 37 to the power of ring operator end exponent equals 5 divided by 3 comma c o s invisible function application 37 to the power of ring operator end exponent equals 5 divided by 4)

STATEMENT-2 : For a block of mass m placed on rough horizontal surface, the minimum horizontal force required to pull the block is mu m g. The minimum force F applied at angle theta (as shown in figure) to pull the block horizontally may be less than mmg. (Where mu is co-efficient of friction)

  1. Statement-1 is True, Statement-2 is True; Statement-2 is a correct explanation for Statement-1.    
  2. Statement-1 is True, Statement-2 is True; Statement-2 is NOT a correct explanation for Statement-1    
  3. Statement-1 is True, Statement-2 is False    
  4. Statement-1 is False, Statement-2 is True    

The correct answer is: Statement-1 is False, Statement-2 is True

A mass m is supported as shown in the figure by ideal strings connected to a rigid wall and to a mass 3m at rest on a fixed horizontal surface. The string connected to larger mass is horizontal, that connected to smaller mass is vertical and the one connected to wall makes an angle 60 to the power of ring operator end exponent with horizontal. Then the minimum coefficient of static friction between the larger mass and the horizontal surface that permits the system to remain in equilibrium in the situation shown is:
