Question

Three point charges q,-2q and 2q are placed on x axis at a distance x=0,x=3/4R and x=R respectively from origin as shown. If q=2×10^(-6) C and R=2 cm, the magnitude of net force experienced by the charge -2q is _____ N.

Correct answer: 5440. The net force on the given charge will be the resultant of the forces due to the other two charges. Hence, the net force F_n can be calculated as follows: F_n = 1/(4πε_0)4q^2R4^2-1/(4πε_0)2q^23R4^2 = 9×10^9×16q^2R^24-2/9 = 9×10^9×16×2×10-6 C^20.02 m^2×34/9 = 5440 N

Three point charges $q, - 2 q$ and $2 q$ are placed on $x$ axis at a distance $x = 0, x = \frac{3}{4} R$ and $x = R$ respectively from origin as shown. If $q = 2 \times 10^{- 6} C$ and $R = 2 cm$ , the magnitude of net force experienced by the charge $- 2 q$ is _____ $N$ .
