When a mass ' m ' is suspended from a spring of length ' ^ , the length of the spring becomes ' L ^ . The mass is pulled down by a distance ' d ' and released. If the equation of motion of the mass is d² x d t² + P ² x=0 , then P is equal to ( g = acceleration due to gravity )

Options

  1. AL - g
  2. Bg L -
  3. Cg L -
  4. DL - g

Correct answer

C. g L -

Step-by-step solution

INTIAL LENGTH =l FINAL LENGTH=L. NET DISTANCE/LENGTH PULLED =L-l T I M E P E R I O D=2 L- g allo, P= 2 T . aligned P=& g L-l . &( option -3) . aligned
