Answer:
The question?
Step-by-step explanation:
we need question to answer
The product of two irrational numbers can be rational or irrational depending on the two numbers. For example, √3×√3 is 3 which is a rational number whereas √2×√4 is √8 which is an irrational number. As √3,√2,√4 are irrational
Given that :
log3=0.477 , log4=0.602 and log5=0.699
Now , as you know that
We have to find the value of
So,=
= 
Now Putting the values of log3, log4 and log5 in the above expression
=1.0079/0.699
=1.5436..
=1.544 (approx)
So, the value of is 1.544(approx).
The surface charge density:
S(igma) = Q / A
A = 1.6 * 10^(-2) * 1.6 * 10^(-2) = 2.56 * 10^(-4) m²
The electric field: E = S / E(psilon) o
E = 0.711 * 10^^(-9) / ( 2.56 * 10 ^(-4) * 8.85 * 10 ^(-12) ) =
= 0.3138 * 10 ^6 = 3.138 * 10^5 V/m
a ) Δ V = E d
Δ V = 3.138 * 10^5 V/m* 1.2 * 10^(-3) m = 376.56 V
b ) When d = 2.40 mm:
Δ V = 3.138 * 10^5 V/m * 2.40 *10^(-3) m = 753.12 V
