Calculate the potential at a point P due to charge of 4 xx 10^(-7)C located 9 cm away. Hence obtain the work done in bringing a charge of 2 xx 10^(-9)C from infinity to the point. P. Does the answer depend on the path along which the charge is brought? |

Answer» SOLUTION :`V=(1)/(4pi epsi_(0)) Q/r= 9 XX 10^(9) xx (4 xx 10^(-7))/(0.09)=4 xx 10^(4)V` `W=qV =2 xx 10^(-9) xx 4 xx 10^(4) =8 xx 10^(-5)J`. No, work done will be path independent (A property of electric field). |
