Lekha Raj 7 years, 3 months ago

A plastic comb gets charge when it is passes through hair .It is due to friction.But wet hair has less friction as compared to dry hairs.Due to this reason ,comb does not get any charge.**This charging with help of the friction also known as charging by rubbing.**I hope this answer is useful for u!!!

Niharika Srivastav 7 years, 3 months ago

1) For equitorial :- 1/ 4 ΠEo r^2 x p cos a(theta). At Equitorial point , a( theta) is 90 so potential becomes zero. 2) For axial :- v=1/4ΠEo.p/r^2

Renuka Lalotra 7 years, 3 months ago

A source charge could be a point charge. We consider source charge as the charge which sends out electric field in all the directions and the effect of that electric field is studied on another charge called test charge. The test charge can also be point charge.
