you can solve this question by calculating the equivalent permittivity between the two charges. Consider the charges and separated by two mediums in series having permittivities epsilon 1 and epsilon 2. The effective permittivity, from my knowledge, would be 2 times epsilon1 * epsilon2 divided by (epsilon1 + epsilon2). Just put this in the Force equation for 2 electric charges with epsilon substituted as the effective epsilon, you`ll get the answer.

You can assume a charge placed at the division of the dielectric spaces and then do it for each set. Then u will get the force on the charge in the middle then dividing it by the charge placed in the middle u will get the electric field . You can use this method to solve problems in a much simpler way
