  2. Electricity and Magnetism CHAPETR 1 Electric forces and Coulombs' law

  3. Properties of electric charges • Coulomb's law • Electric force due to point charge • Electric forces due to group of charges.

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

  5. 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?

  6. 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?

  7. 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 ?
