Vedclass · Answer

(A) The electric potential $V$ at the center of a circle due to multiple point charges is the algebraic sum of the potentials due to each individual charge.$V = \sum \frac{k q_i}{r}$,where $k = 9 	imes 10^9 \ N \cdot m^2/C^2$ and $r = 0.4 \ m$.Sum of charges $Q_{total} = (+5 - 5 + 7 - 5 + 11 + 7 + 15 - 7) \ \mu C = 28 \ \mu C = 28 	imes 10^{-6} \ C$.$V = \frac{9 	imes 10^9 	imes 28 	imes 10^{-6}}{0.4} = \frac{9 	imes 28 	imes 10^3}{0.4} = \frac{252 	imes 10^3}{0.4} = 630 	imes 10^3 \ V = 63 	imes 10^4 \ V$.
