Expert Mdcat: Expert Emergency Series 2020 F.Sc. (Part-II)

This document contains a practice test for the MDCAT exam covering electrostatics. It has two sections - short questions worth 20 marks total with 2 marks each for 10 questions, and long questions worth 10 marks total with 5 marks each for 2 questions. The short questions cover topics like electric field lines, potential gradient, Gauss's law, capacitors, and Coulomb's law. The long questions ask about defining capacitors and calculating the zero field location for two point charges.
