Question # Two charges ( 9 e ) and ( 3 e ) are placed at a separation ( r ). The distance of the point where the electric field intensity will be zero, is :

# Two charges ( 9 e ) and ( 3 e ) are placed at a separation ( r ). The distance of the point where the electric field intensity will be zero, is :

(1) ( frac{r}{(1+sqrt{3})} ) from 9e charge

(2) ( frac{sqrt{3} r}{sqrt{3}+1} ) from ( 9 e ) charge

(3) ( frac{r}{(1-sqrt{3})} ) from ( 3 e ) charge

(4) ( frac{sqrt{3} r}{1+sqrt{3}} ) from ( 3 e ) charge

Solution

The question is solved above.
