Which type of rebalancing technique use voltage applied to pendulum and electrode for correction?

Which type of rebalancing technique use voltage applied to pendulum and electrode for correction? Correct Answer Voltage forcing

In potential forcing, a potential is applied to the pendulum and to one or both the electrodes. The voltage establishes electric fields that induce the charge of the nonconducting pendulum. This causes a net force to act on the proof mass.
