SUMMARY
The total induced charge on a grounded conducting plane due to a positive charge Q located at a distance L above it is -Q. This conclusion is derived from the principle of image charges, where the induced surface charge is equal and opposite to the external charge. The presence of charge Q attracts negative charge to the surface of the conducting plane, resulting in an induced charge of -Q, as confirmed by the derivation found in Griffith's "Introduction to Electrodynamics".
