Force of a charge placed at the centeriod of triangle

Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.). The process of converting one form of energy to another is known as transduction.

Explanation:

When four equal charge placed on vertices of triangle then force on test charge at centre is zero.
