Questions
If the electric potential at a distance of 10 cm from a point charge is -2 volt, intensity of electric field at that point is
detailed solution
Correct option is C
For a point charge, V=14π∈o.Qrand E=14π∈o.Qr2∴E→=Vr=20.1V/m=20 V/mSince the potential is negative, the charge must be negative and hence the field is directed towards the charge.Talk to our academic expert!
