Given:

  • ABC is a right angled triangle with AB=3cm and BC=4cm.

  • Charge at A = 15×10^-6C, charge at B = 12×10^-6C, charge at C = -20×10^-6C.



To find: Net force acting on charge at B due to the remaining charges.

Solution:

  • Step 1: Calculate the distance between the charges.


    • Distance between A and B, AB = 3cm.

    • Distance between B and C, BC = 4cm.

    • Distance between A and C, AC = √(AB^2 + BC^2) = 5cm.


  • Step 2: Calculate the force between the charges.


    • Force between A and B, FAB = k(Q1Q2/r^2) = 9×10^9 × (15×10^-6) × (12×10^-6) / (3×10^-2)^2 = 1.08×10^-3 N.

    • Force between B and C, FBC = k(Q1Q2/r^2) = 9×10^9 × (12×10^-6) × (20×10^-6) / (4×10^-2)^2 = -1.08×10^-3 N (negative because charges are of opposite sign).


  • Step 3: Calculate the net force on charge at B.


    • Since charge at B is at the right angle of the triangle, forces FAB and FBC will act at 90 degrees to each other.

    • Net force on charge at B, FBnet = √(FAB^2 + FBC^2) = √((1.08×10^-3)^2 + (-1.08×10^-3)^2) = 1.53×10^-3 N.




Answer: The net force acting on the charge at B due to the remaining charges is 1.53×10^-3 N.
