For a particle performing S.H.M., when displacement is 'x', the potential energy and restoring force acting on it is denoted by 'E' and 'F' respectively. The relation between x , E and F is

Options

  1. AE F +x=0
  2. B2 E F +x=0
  3. CE F -x=0
  4. D2 E F -x=0

Correct answer

B. 2 E F +x=0

Step-by-step solution

Displacement =x, P.E. =E, Force =FF=-k xE= 1 2 m ² x²= 1 2 k x²2 E=(-) F x x²=(-) F x 2 E F +x=0
