Question
Three point charges 8×10−9C,32×10−9 C and 24×10−9C are placed at the corners A,B, and C of a square ABCD having side 0.04 m. Calculate the magnitude of electric intensity at the corner D.
Open in App
Solution
qA=8×10−9C
qB=32×10−9C
qC=24×10−9C
Electric field intensity at D:ED=kqAr2AD+kqBr2BD+kqCr2CD where rAD is the distance between A and D and so on..
