hello guizz my name is ahmed yaseen gaad and i give chalangez questions my first question=
1=two point charges placed at distance of 20cm in air repel each other with a certain force.when a dielectric slab of thickness 8cm and dielectric constant k is introduced b/w these point charges ,force of interaction becomes half of its previous value then k is approximately??
ans=4 i want solution not answer if u can't do this problem then my email address is
=samigaad.yg@gmail.com you can get this question sol; from aboveemail and ucan also send me toughest qution i wil ans u every one of them
