I think 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.

F=K(Qq\r^2)

two charges in two different medium, say Q is in air and q is in water ?

- 4 years, 2 months ago

those two are same charged?positive or negative?

- 4 years, 2 months ago

it doesn't matter... say both are positive

- 4 years, 2 months ago

force of attraction can be calculated as F=Qq4*3.142E divided by r^2
