Question

3 equal charge having a magnitude of 2 micro coulomb are placed at the three corner of a right angle triangle of side 3cm,4cm and 5cm .then find the force on the charge at the right angle corner

Answer 1

Three equal charges each 

2μC

are placed the comers of a right angled triangle ABC. The force on charge at B due to charge at A is                 

F⃗ 1=14πε0(2μC)(2μC)(AB)2

                         (along BA) 

F⃗ 1=14πε04×10−12(0.03)2N

                               (along BA)  The force on charge at B due to charge at C is 

F⃗ 2=14πε0(2μC)(2μC)(BC)2

          (along BC) 

F⃗ 2=14πε04×

Hope it helps....
