SUMMARY
The electric field magnitude midway between two charges, Q1 = 1 C and Q2 = 11 C, separated by 2 m, is calculated using the formula E = k(Q/r²). The user initially calculated the electric fields due to each charge separately, yielding 9E9 N/C for Q1 and 1.8E10 N/C for Q2. However, the correct approach requires considering the direction of the electric fields, leading to a net electric field of 1.35E10 N/C towards Q2, not simply adding the magnitudes.
