By volume conservation of the fluid on both sides we can say that volume of fluid displaced on the side of the car must be equal to the volume of fluid on the other side
so we have



so the car will lift upwards by distance 1.2 m and the other side will go down by distance 15.55 m
So here the net pressure on the smaller area is given as

excess pressure exerted on the smaller area is given as


now the force required on the other side is given as



Answer: all the energy is rushed in the wires due to the swich turning on when touching it may start a fire or electricute
