Question

Calculate the thrust exerted by the atmosphere on a rectangular plate of length 10 cm and breadth 7 cm.

Answer 1

3cm as benn find the 10cm &less the 7

Answer 2

Answer:

as pressure= thrust/area

therefore thrust force= pressure×area

so... F th= 1 bar atm pressure×arra of rectangle

= 1×2(L+B)

=2{10+7}

=2(17)

=34 newtons.

and done
