SBT Electrostatics Q46 & Q47 | Tricky Electrostatics Problems | JEE / NEET

Описание: SBT Electrostatics Q46 & Q47 | Tricky Electrostatics Problems | JEE / NEET

In this video, I solve two important conceptual problems from Electrostatics SBT that frequently challenge students due to symmetry and electric field analysis. These are Question No. 46 and Question No. 47, explained step by step with clear reasoning.

🔹 Question 46

Consider a uniformly charged hemispherical shell.
What can you say about the direction of the electric field at a point lying on the equatorial plane of the hemisphere

In this question, we analyze the symmetry of charge distribution on a hemispherical shell and determine the direction of the resultant electric field at a point on its equatorial plane by resolving field components.

🔹 Question 47

Consider a uniformly charged thin spherical shell as shown in the figure.
The radius of the shell is R.
The electric field at point P is E.
Find the electric field at point Q, given that x less than R.

Coordinates of point P: x, 0, 0

Coordinates of point Q: −x, 0, 0

This problem is based on the properties of electric fields due to a uniformly charged spherical shell and uses symmetry and Gauss’s Law to compare the electric fields at two symmetric points inside the shell.
