Universal Gravitational Constant – 1L10.00

Cavendish Balance – 1L10.30


  • Initially the balance is in equilibrium with the two large lead balls in one extreme position up against the face of the balance.
  • At the start of the lecture the balls are moved to the other extreme position.
  • The suspension goes into oscillation.
  • By the end of the period the motion of the suspension approaches a new equilibrium position brought about by the change in the gravitational force on the dumbbells.
