What do you understand by principle of superposition ?

Explanation

The principle of superposition states that when number of charges are interacting the total force on the given charge is the vector sum of the individual forces exerted on the given charge by all the other charges

`vecF_(2)=vecF_(21)+vecF_(23)+....+vecF_(2n)`
i.e , `vecF_(2)=(1)/(4piepsilon_(0))((q_(2)q_(1))/(r_(21)^(2))hat(r)_(12)+(q_(2)q_(3))/(r_(23)^(2))hat(r)_(32)+....+(q_(2)q_(n))/(r_(2n)^(2))hat(r)_(n2))`
