Question
Three point charges 1C, 2C and 3C are placed at the corners of an equilateral triangle of side 1m. The work required to move these charges to the crones of a smaller equilateral triangle of side 0.5 in two different ways as fig. (A) and fig (B) are Wa and Wb then :
Options
A.Wa > Wb
B.Wa < Wb
C.Wa = Wb
D.Wa = 0 and Wb = 0
Solution
Work done by external force = ᐃU [It is state function]
