Answer : Negative charge

Explanation :

An electrostatic precipitator is a device that is used to remove dust particles and smoke from a gas.

It consists of a stack of plates. The gas flows via the spaces between the wires. Then it passes to the stack of plates.

A high voltage power supply is applied between wires and the plates. A positive charge is applied to the set of wires and a negative charge is applied to the plates.
