Three identical charged balls each of charge 2 C are suspended from a common point P by silk threads of 2 m each (as shown in figure ) . They from an equilateral triangle of side 1 m .
The ratio of net force on a charged ball to the force between any two charged balls will be :

Text Solution

Verified by Experts

The correct Answer is:
D

Net force on are charge
`F_(q)=sqrt(F^(2)+F^(2)+2"FF"cos60^(@))`
= `sqrt(3)` F
Where F is force b/w any two charges
So `(F_(q))/F = sqrt(3)`
