1.	Three charges + 20 esu, -25 esu and +50 esu are placed at the points A, B and C respectively on a straight line. What force willact on the charge placed at B ? Given AB = 10 cm; BC = 15 cm.
Answer» i solved it (easy ONE) here are the snaps ...i numbered corners as 1,2,3 & 4i CALCULATE FORCE on 2 due to 1,3 & 4F21 = force on 2 due to 1F23 = force on 2 due to 3F is RESULTANT of F21 & F23 directed towards diagonaladd them by vector resultantF24 is also in the same DIRECTION along diagonalso net forceFnet = F24 + F
