Question

calculate the presure exeated by a body when a force of 2.5 newton acts on an area of ceross section 10cm^
2

Answer 1

Answer:

Explanation:since pressure=Force/Area

when it is placed upright its length and breadth will be 10 & 5 respectively

so area=10*5=50cm2=

0.005m2

Pressure=2.5N/0.005m2

=500N m-2

in case b it is placed on widest base i.e. 25cm

so area =25*10=2500cm2

=0.25m2

Pressure=2.5/0.25=10N m-2
