To solve the problem of finding the increment in tension in the ring when a charge \( q \) is placed at the center, we can follow these steps: ### Step 1: Understand the Setup We have a ring of radius \( R \) with a uniformly distributed charge \( Q \) on it. A point charge \( q \) is placed at the center of the ring. ### Step 2: Calculate the Linear Charge Density The linear charge density \( \lambda \) of the ring can be calculated as: \[ ...
