When t<0,V1 and V2 are voltages of capasistors,when t>0,R3 becomes infinite,find V3(t).

I can get when t=0+,V3=V1-V2,then I wanna find the V3(t>0).
I try to use Laplas circuit,but I can't find the equition of V3,Please help.

Can you derive the equation for the terminal on the left side of the gap?

Can you derive the equation for the terminal on the right side of the gap?
