JEE Adv 2020 PYQ in 30s! 🤯 Taylor Series SHM Trick (PART 1)

Think JEE Advanced Previous Year Questions always take 10 minutes to solve? Let's crack a classic Simple Harmonic Motion (SHM) problem from JEE Advanced 2020 in just 30 seconds using the Taylor series expansion!

​When a potential energy function U(x) looks overly complex, mathematical expansions are your best friend. By expanding the function around the stable equilibrium position, all the higher-order terms become negligible for small oscillations. You are left directly with the x^2 term, which perfectly matches the standard U = 1/2kx² form. Once you extract k, you instantly have your time period using T= 2pi [sqrt(m/k)]

​This is a must-know mathematical tool for saving time in competitive physics. Add this short to your revision playlist and let me know which PYQ we should destroy next!
