In this post, I am sharing Class 12 Physics Chapter 12 Short Questions and Numerical Notes PDF for the students of Intermediate Part 2. This chapter’s name is Electrostatics. Students can download the Class 12 Physics Chapter 12 Short Questions and Numerical Notes PDF on their laptop or mobile. These Physics Notes are for all the boards working under the Punjab Board like Gujranwala Board, Lahore Board, Faisalabad Board, Multan Board, Rawalpindi Board, Sargodha Board, DG Kahn Board, and Sahiwal Board. Here are the complete FSC 2nd Year Physics Notes PDF chapters.
FSC Part 2 Physics Chapter 12 Short Questions and Numerical
Electric Lines of force never cross why?
Electric line of force can never cross each other.
Reason: As electric intensity is a vector quantity and if two electric lines of force cross each other at a single point then electric intensity will have two different directions at a single point which is not possible because electric intensity is a vector quantity and vector has only one direction.
If a point charge q of mass m is released in non-uniform electric field with field line in the same direction pointing, will it make a rectilinear motion?
If a point charge q of mass m is released in a non-uniform electric field then there are two possibilities:
(i) If a point charge is released in a non-uniform field produced by positive and negative charges then it will move in a curved path.
(ii) If a point charge is placed in no-uniform field produced by a positive or negative charge then it will make a rectilinear motion.
Do electrons tend to go to region of high potential or of low potential?
As electrons are negatively charged particle therefore when they enter the electric field they will tend to go the region of high potential (positive terminal) from the region of low potential (negative terminal).
