भतक क पसतक (translated as "A Comprehensive Book on Basic Physics") is an Android application developed by MrSLee, available for free. The app falls under the Education & Reference category and aims to provide a comprehensive understanding of the fundamental concepts of physics. The app includes hundreds of multiple-choice questions that cover the basic principles of physics.

The questions are based on various topics such as energy, force, electricity, waves, magnetism, lenses, medical physics, atoms, and graphs. Each question provides a detailed explanation to help the user understand the concept better. The app also features a navigation system that allows users to move to the next or previous question with ease. However, there is no star rating system to show the user's progress.
