Question

A bead of mass m is fitted on a rod and can move on it without friction. Initially the bead is at the middle of the rod and the rod moves translationally in a vertical plane with an acceleration a subscript 0 end subscript in a direction forming an angle alpha with the horizontal plane. The acceleration of bead with respect to rod is

  1. g sin invisible function application alpha    
  2. open parentheses g plus a subscript 0 end subscript close parentheses sin invisible function application alpha    
  3. g sin invisible function application alpha plus a subscript 0 end subscript cos invisible function application alpha    
  4. g sin invisible function application alpha minus a subscript 0 end subscript cos invisible function application alpha    

The correct answer is: g sin invisible function application alpha minus a subscript 0 end subscript cos invisible function application alpha



    m g sin invisible function application alpha minus m a subscript 0 end subscript cos invisible function application alpha equals n a rightwards double arrow a equals g sin invisible function application alpha minus a subscript 0 end subscript cos invisible function application alpha
