Two point charges 5 xx 10^(-8) C and 3 xx 10^(-8)C are locate 16 m apart. At what points on the line joining the two charges is the electric potential zero ?

Answer»

Solution :`V = (1)/(4PI epsi_0) q/r`
Between the two CHARGES
`(1)/(4pi epsi_0 )(q_1)/(X) = (1)/(4pi epsi_0) ((q_2)/(16-x))`
10 cm from +ve charge
Outside the two charges
`(1)/(4pi epsi_0) (q_1)/(x) = (1)/(4pi epsi_0) ((q_2)/(16 + x))`
40 cm from +ve charge
