Two point charges (q_(1) and q_(2)) are placed on x-axis, figure shows graph potential (V) on x-axis. With x-co-ordinate:

Answer»

`q_(1)GT0`
`q_(1)=(x_(1))/(x_(2))q_(2)`
`|q_(1)|lt|q_(2)|`
`|q_(1)|gt|q_(2)|`

Solution :Potential near `q_(1)` is `+infty` so `q_(1)gt0` potential near `q_(2)` is `-infty` so `q_(2)lt0` potential is zero `x_(2)ltx_(1)` so `|q_(1)|gt|q_(2)|`
