SBT Electrostatics Q51 & Q52 | Electric Field Because of Line Charge And Charged Arc | JEE / NEET

Описание: SBT Electrostatics Q51 & Q52 | Electric Field Because of Line Charge And Charged Arc | JEE / NEET

In this video, we solve two important electrostatics problems from the SBT book (Questions 51 and 52) involving electric field due to a charged line bent into a circular shape.

🔹 Question 51

An infinitely long line charge is bent in a U-shape as shown in the figure.
The semicircular part has radius R and linear charge density λ.
Using the results obtained in the previous problems, we calculate the electric field intensity at the center of the circle.

🔹 Question 52

Repeat the above problem if the semicircular part is replaced with a quarter circle.

✨ What you’ll learn in this video:

Formula for electric field due to a finite straight line charge

Formula for electric field due to a charged arc of a circle

Step-by-step application of these formulas

Clear comparison between semicircular and quarter circular charge distributions

Conceptual understanding useful for board exams, JEE, and competitive exams

This video is especially helpful if you want to understand how standard electrostatics formulas are applied in complex geometries rather than just memorizing results.
