In hypothetical experiment, we observe a 2 Au NPs with diameter of 100 nm and with the distance from their surfaces of 20 nm. The particles are suspended in the solution in which precursors for MgO precipitation are added. After 10 minutes, the Au NPs are coated with 15 nm thick shell of MgO. Find out/calculate the % of the magnitude of WV interaction change between NPs due to oxide shell growth. Assume that distance between NPs remains the same. Considering your results, discuss the last assumption about distance between NPs remaining the same.
