Electricity and Magnetism 3rd Level Students

231 Phys-4


Electricity and magnetism 3 rd level students

  • Electricity and Magnetism

CHAPETR 1

Electric forces and Coulombs' law


Electricity and magnetism 3 rd level students

  • Properties of electric charges

  • Coulomb's law

  • Electric force due to point charge

  • Electric forces due to group of charges.


Electricity and magnetism 3 rd level students

Ex. 1 Three point charges placed on a horizontal line as shown in Fig.1. Find the net force acting on q2?


Electricity and magnetism 3 rd level students

Ex.2Three charges lie along x-axis, q1=+9 µc placed at the origin and q2= +16 µc placed at x = 90 cm. Where a negative charge q3 must be placed between them such that, the net force acting on it is zero?


Electricity and magnetism 3 rd level students

  • Home work

Ex. 3 Three point charges [q1= q3=+5µc and q2=+2µc] are located at the corners of a triangle as in Fig.

  • Find the net electric force acting on q2?

  • Home work

Ex.4Two point charges q1= q2=+2µc located at x = 0 and y = 30 cm and x = 0 and y = - 30 cm, respectively.

  • Calculate the magnitude and direction of the net force acting on a third point charge,q3 =+4µc placed at x = 40 cm and y = 0 ?
