Below is an attachment containing the solution to the question.
For Pascal's principle, the pressure exerted on the first piston is equal to the pressure exerted on the second piston:

which means

where F1, F2 are the two forces and A1, A2 the areas of the two pistons.
The areas of the pistons are:


And the force on the second piston is

, so the force that should be applied on the first piston is
Solar radiation is the fundamentalenergy driving our climate system, and nearly all climatic and biologicprocesses on Earth are dependent on solar input. Energy from the sun isessential for many processes on Earthincluding warming of the surface, evaporation, photosynthesis and atmospheric circulation.
