Question

4 point charges +10nc,-20nc,+20nc,-10nc are placed at the corner of
square pqrsof side 0 05 calculate the magnitude and direction of
electric intensity at the centre of the sphere ?

Ved Prakash Lakhera · Accepted Answer

the length of diagonal of a square of length 0
05m=25×10-4+25×10-4=52×10-2m
the distance of centre of the square from each of the corners of the square pqrs=52×10-2m
the electric field at the centre of the square due to charges +10nC, -20nC, +20nC,-10nC is given by,E=14πε0+10-20+20-1025×10-4×2×10-9=0

4 point charges +10nc,-20nc,+20nc,-10nc. are placed at the corner of square pqrsof side 0.05. calculate the magnitude and direction of electric intensity at the centre of the sphere ?
