Conisder a system of three charges q//3,...

Conisder a system of three charges `q//3`, `q//3` and `-2q//3` placed at point A, B and C, respectively, as shown in the figure. Take O to be centre of the circle of radius R and angle `CAB=60^@`

A

the electric field at point O is `q//8piepsilon_0R^2` directed along the negative x-axis.

B

the potential energy of the system is zero

C

the magnitude of the force between the charges at C and B is `q^2// 54 piepsilon_0R^2`.

D

the potential at point O is `q //12piepsilon_0R`

Text Solution

Verified by Experts

`F_(BC)=(1)/(4piepsilon_(0))(((q)/(3))((2q)/(3)))/((R//sqrt(3))^(2))=(q^(2))/(54piepsilon_(0)R^(2))`
