Question

A solution contains non volatile solute of molecular mass M subscript 2 end subscript. Which of the following can be used to calculate the molecular mass of solute in terms of osmotic pressure -

  1. straight M subscript 2 equals open parentheses straight m subscript 2 over pi close parentheses VRT    
  2. M subscript 2 end subscript equals open parentheses fraction numerator m subscript 2 end subscript over denominator text end text V end fraction close parentheses fraction numerator R T over denominator pi end fraction    
  3. straight M subscript 2 equals open parentheses m subscript 2 over straight V close parentheses pi RT    
  4. straight M subscript 2 equals open parentheses straight m subscript 2 over straight V close parentheses pi over RT    

The correct answer is: M subscript 2 end subscript equals open parentheses fraction numerator m subscript 2 end subscript over denominator text end text V end fraction close parentheses fraction numerator R T over denominator pi end fraction

When a force F is applied on a block of mass m resting on a horizontal surface then there are two possibilities, either block moves by translation or it moves by toppling. If the surface is smooth then the block always translates but on a rough surface it topples only when the torque of the applied force F is greater than the torque of mg about a point in contact with the ground. When the force F is applied the body may topple about A or it may translate. If the block is a cube of edge a and mu = 0.6 then :-
