answered-by-expert Expert Answer
Mass, m = 2 kg
 
Acceleration due to gravity, g = 9.8 m / s2
 
Weight , W = 2 × 9.8 = 19.6 N

begin mathsize 12px style straight l equals 6 space cm equals 6 cross times 10 to the power of negative 2 end exponent space straight m
rightwards arrow straight A equals straight l squared equals open parentheses 6 cross times 10 to the power of negative 2 end exponent close parentheses squared equals 36 cross times 10 to the power of negative 4 end exponent space straight m squared
Pressure equals Force over Area equals fraction numerator 19.6 over denominator 36 cross times 10 to the power of negative 4 end exponent end fraction equals 0.5444 cross times 10 to the power of 4
rightwards arrow Pressure equals 5444 space Pa

end style
