To solve this problem we will apply the mathematical consideration of the electric field on an axial axis of a ring. This definition is already established mathematically and is a subordinate of the definition of the magnetic field of Coulomb's laws. It can be expressed as,
![E = \frac{kQx}{\sqrt{(x^2+R^2)^3}}](https://tex.z-dn.net/?f=E%20%3D%20%5Cfrac%7BkQx%7D%7B%5Csqrt%7B%28x%5E2%2BR%5E2%29%5E3%7D%7D)
Here,
k = Coulomb's constant
Q = Charge
x = Distance on the axial line
R = Radius of the circle or ring
At x = 1 cm, we have that the total charge is 66.0 μC and the radius 0.1m, then replacing,
![E = \frac{(9*10^9)(66*10^{-6})(0.01)}{\sqrt{((0.01)^2+(0.1)^2)^3}}](https://tex.z-dn.net/?f=E%20%3D%20%5Cfrac%7B%289%2A10%5E9%29%2866%2A10%5E%7B-6%7D%29%280.01%29%7D%7B%5Csqrt%7B%28%280.01%29%5E2%2B%280.1%29%5E2%29%5E3%7D%7D)
![E = 5.85*10^6 N/C](https://tex.z-dn.net/?f=E%20%3D%205.85%2A10%5E6%20N%2FC)
Therefore the electric field on the axis of the ring is 5.85MN/C
Resistance adds up in series and voltage through all resistors as a total adds up to the voltage supply
Answer:
The time is 176 seconds
Explanation:
We use the formula:
V= d/t V=velocity, d= distance, t= time
259 m/s= 45683 m/ t
t= 45683 m// 259 m/s
t= 176, 3 seg
Answer:
Hydraulic pressure exerted on glass slab, ρ=10 atm
Bulk modulus of glass, B=37×10^9 Nm^−2
Bulk modulus, B=P/(ΔV/V)
where,
ΔV/V= Fractional change in volume
ΔV/V=P/B
=10×1.013×10^5 /(37×10 ^9)
=2.73×10^-5
Therefore, the fractional change in the volume of the glass slab is 2.73×10^-5
