Determine the Minimum Velocity of a Charged Ball for Complete Revolution ||

In this video, we explore a conceptually rich and insightful question from the IIT-JEE 2001 paper that integrates ideas from both Electrostatics and Circular Motion, making it an essential problem for all students preparing for competitive exams like IIT JEE Main, IIT JEE Advanced, and NEET. The question focuses on determining the minimum horizontal velocity required for a charged pendulum-like system to complete a full circular revolution, showcasing the beautiful interplay of electric and mechanical forces.

📌 "A small ball of mass 2×10⁻³ kg having a charge of 1 μC is suspended by a string of length 0.8 m. Another identical ball having the same charge is kept at the point of suspension. Determine the minimum horizontal velocity which should be imparted to the lower ball so that it can make complete revolution."

This video is crafted specifically for class 12 students from various educational backgrounds who are diving deep into Physics preparation for engineering and medical entrance exams. We break down the problem into its fundamental concepts, using clear and intuitive explanations in Hindi to ensure maximum conceptual clarity. This makes it a perfect resource for those who are focusing on IIT JEE Previous Years' Question Solutions, especially for mastering high-level Electrodynamics and Mechanics problems.

Understanding how a charged body behaves under electrostatic repulsion while also being subject to circular motion constraints is a crucial skill for any serious aspirant. In this video, we explore how the forces act in different directions, how equilibrium is disturbed to initiate motion, and what conditions must be met for the body to make a complete vertical revolution. Such advanced applications of concepts are not only relevant for IIT-JEE Advanced PYQ practice but also form the basis of many NEET PYQ level problems in Physics.

This particular problem challenges students to combine their understanding of centripetal force, tension in strings, and electrostatic repulsion between like charges. By the end of the video, students will not only learn how to approach and solve this specific problem, but also gain the confidence to tackle other problems involving multiple force systems and non-linear motion.

Our focus in this video is not merely on arriving at the answer, but on helping you develop a logical and analytical approach toward solving complex Physics problems. The strategy used here emphasizes conceptual clarity, visualization techniques, and systematic analysis, all of which are crucial for excelling in entrance exams like IIT-JEE and NEET.

If you're a class 12 student aiming to build a strong foundation in Physics and secure a top rank in IIT JEE Main, IIT JEE Advanced, or NEET, this video offers you an excellent opportunity to learn from actual exam questions and understand the mindset required to solve them efficiently. Additionally, since this is a part of our IIT JEE Previous Years' Question Solutions series, you’ll find the level of discussion and depth tailored to help you master the subject at a competitive level.

Don’t miss this in-depth analysis and explanation of one of the most interesting and instructive problems from IIT-JEE 2001. It’s an excellent resource for anyone looking to enhance their problem-solving skills and grasp of core Physics concepts. This video adds great value to your exam preparation journey by bridging the gap between theoretical concepts and their practical applications in problem-solving scenarios.
