A body of mass 100kg exerts pressure of 50.000N\M².calculate the area over which the force acts

the area is 0.0196 m^2

Explanation:

Recall that pressure is defined as the force over the surface area:

Pressure = Force / Area

Therefore, Area =  Force / Pressure

in our case, the acting force is the gravitational force Fg = m * g = 100 * 9.8 N = 980 N

and the pressure is 50000 N/m^2

Then the acting area is:

980 / 50000 m^2 = 0.0196 m^2

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
