An unknown point charge q is 6.0 m away from another point charge Q, 3.0mu * C as shown in the figure. What is the magnitude of the electric field experienced by the point charge q due to the point charge Q? Use k as 9 * 10 ^ 9 * N * m ^ 2 * C ^ - 2

My answer is opptionc, just check with anyone else

Idk
