Question

a cube of ion with each side of 1cm is lying on a table . find the pressure exerted by the block on the table?​

Answer 1

Answer:

a cube of ion with each side of 1cm is lying on a table.

Pressure is given as force/area

 Force, F = mg = 1000 X 981 gm.m/s2

and area, A = 1x1 cm2 = 1 cm2

thus,

the pressure exerted would be  P = (981 X 1000) / 1

or  P = 9.81 X 105 Ba

Answer 2

Answer:

Pressure is equal to force/area.

Where Force, which is denoted by F = mg

Considering g=10 m/s2

Then,

Force = 1000 X 1000 gm.cm/s2

while area which is denoted by A = 1x1 cm2 = 1 cm2.

Thus, the pressure will be as  

P= (1000 X 1000) / 1

P = 1 x 10 6 pa

WHERE Pa is unit of pressure known as Pascal
