Question

Suppose that the hatch on the side of a Mars lander is built and tested on Earth so that the internal pressure just balances the external pressure. The hatch is a disk 50.0 cm in diameter. When the lander goes to Mars, where the external pressure is 650 N/m², what will be the net force (in newtons and pounds) on the hatch, assuming that the internal pressure is the same in both cases? Will it be an inward or an outward force?

Answer 1

Ansuper Internal Pressure = External Pressure on surface earth External force is Text = Parma = (1,018 x los pa) 61 25 Text = 1988N Now external force on the disk when it is on mars is Fexd - (650) a (6.252 = 127.56N Internal force on the disk is find = 19880N

Therefore

The Net force on the disk is

Fnet = 19880N – 127.6N

which gives us

Fnet = 19752.4N
or
Fnet = 4440.516183lbs

or

Fnet 19.8kN

It will be an outward force
