A point charge is
Answer :
Option (c) is correct:
In an electric field, if a positive charge is placed, then the charge itself will generate some electric field on its own diverging from the point.
At a nearby point Q (towards the direction of external field), the field will increase as the field lines from the charge will also add to external field lines.
At a nearby point P (away from the direction of external field), the field will decrease as the field lines from the charge will cancel some of the external field lines.
Therefore, at a nearby point, field can either increase or decrease.
Option (d) is correct:
In an electric field, if a negative charge is placed, then the charge itself will generate some electric field on its own converging to the point.
At a nearby point Q (towards the direction of external field), the field will decrease as the field lines from the charge will cancel some of the external field lines.
At a nearby point P (away from the direction of external field), the field will increase as the field lines from the charge will add on to the external field lines.
Therefore, at a nearby point, field can either increase or decrease.
